Dale Carnegie’s book “How to Win Friends and Influence People” has sold over 30 million copies worldwide, making it one of the bestselling books in history. Yet most people who’ve heard his name have never actually read his work or applied his principles.
I’m going to show you everything about Carnegie: his fascinating life story, the books that changed millions of lives, the courses that continue his legacy, and most importantly, the specific principles you can apply today to improve your relationships, career, and influence. Whether you’re struggling with communication, leadership, or just want to connect better with people, Dale Carnegie’s wisdom remains as relevant now as it was nearly a century ago.
Before we dive into his teachings, let’s understand the man behind the principles.
Dale Carnegie was born Dale Carnagey on November 24, 1888, in Maryville, Missouri. He grew up on a farm in poverty, where his family struggled financially throughout his childhood.
The Humble Beginnings: Young Carnegie milked cows, cut wood, and did farm chores before and after school. His family was so poor they couldn’t afford to board him at the state teachers’ college, so he commuted on horseback each day.
Despite these hardships—or perhaps because of them—Dale Carnegie developed a hunger for self-improvement and success that would define his entire life.
At State Teachers College in Warrensburg, Missouri, Dale Carnegie discovered something that changed everything: public speaking and debate.
The Transformation: He joined the debate team and began winning competitions. For the first time, this poor farm boy found something he excelled at—communicating and persuading others. This discovery became the foundation of everything Dale Carnegie would later teach.
After college, Dale Carnegie took various jobs:
Each failure taught him valuable lessons about human nature, sales, and influence. These experiences, though painful at the time, provided the real-world education that would later make Dale Carnegie one of the most influential teachers of his generation.
In 1912, at age 24, Dale Carnegie approached the manager of a YMCA in New York City with a proposition: let him teach a class on public speaking to businessmen.
The Deal: The YMCA wouldn’t pay him a salary. Instead, Dale Carnegie would work on commission—receiving a percentage of the net proceeds if the class was profitable.
The class was an immediate success. Word spread quickly, and within a short time, Dale Carnegie was earning $30 per night (equivalent to about $850 today)—more than most college professors made in a week.
Let’s explore the books that made Dale Carnegie a household name.

What You’ll Gain:
Common Positive Feedback:
Common Criticisms:
The Verdict: For people committed to personal development and willing to invest time and money, the Dale Carnegie Course delivers significant value. However, you can also gain tremendous benefit just by reading Dale Carnegie books and applying the principles on your own.
This book deserves special attention because it’s arguably the most influential personal development book ever written.
Before Dale Carnegie, self-help books focused on building character through willpower and moral virtue. Dale Carnegie took a different approach: focus on understanding human nature and working with it, not against it.
The Revolutionary Shift: Instead of changing yourself fundamentally, Dale Carnegie taught that you could achieve more by changing how you interact with others. This practical, behavior-focused approach made self-improvement accessible to everyone.
In Professional Settings:
Principle: Give honest and sincere appreciation
Principle: Remember names
Principle: Be a good listener
In Personal Relationships:
Principle: Don’t criticize or complain
Principle: Show genuine interest
Principle: Admit when you’re wrong
Modern psychology has validated many Dale Carnegie principles:
Reciprocity: When you give appreciation, people naturally want to reciprocate. Dale Carnegie understood this decades before it was formally studied.
Confirmation Bias: People seek information that confirms their existing beliefs. Dale Carnegie’s advice to let others feel ideas are theirs works because people are more committed to their own ideas.
Social Proof: We’re influenced by what others do. Dale Carnegie’s emphasis on giving people a reputation to live up to leverages this principle.
Emotional Intelligence: Dale Carnegie essentially taught emotional intelligence before the term existed—recognizing and managing emotions in yourself and others.
Let’s help you choose the right starting point.
For Most People:
This progression builds from external relationships to internal peace to effective expression.
This question often arises because Dale Carnegie frequently referenced faith and spiritual principles in his work.
Dale Carnegie was raised in a Christian household and maintained Christian beliefs throughout his life, though he wasn’t rigidly denominational.
His Approach:
“How to Win Friends and Influence People”: While not explicitly religious, the book embodies Christian principles like:
“How to Stop Worrying and Start Living”: This Dale Carnegie book contains more explicit religious content:
What makes Dale Carnegie’s work powerful is that his principles transcend religious boundaries. You don’t need to share his faith to benefit from his teachings—the principles work because they’re based on human psychology and genuine respect for others.

Reading about Dale Carnegie is one thing. Applying his principles is what creates results.
Day 1-2: Don’t Criticize Challenge yourself to go two full days without criticizing anyone—not out loud or even in your head.
Day 3-4: Give Appreciation Find three people each day to genuinely appreciate. Be specific about what they did and why it mattered.
Day 5-7: Remember Names Practice the Dale Carnegie name technique: repeat the name immediately, use it during conversation, create a memory association.
Day 8-10: Smile More Consciously smile at everyone you interact with. Notice how they respond differently.
Day 11-13: Show Interest Ask at least five questions about the other person for every statement about yourself.
Day 14: Active Listening In every conversation today, practice Dale Carnegie’s listening principle: focus completely on the speaker without planning your response.
Day 15-17: Avoid Arguments When you disagree, practice saying “You might be right, I’ve been wrong about things before. Let me think about this.”
Day 18-20: Admit Mistakes Quickly When wrong, beat others to the punch by admitting it immediately and emphatically.
Day 21: See Others’ Perspectives Before every interaction, ask yourself: “How does this situation look from their point of view?”
Day 22-24: Begin with Praise Before offering criticism or requesting changes, start with genuine appreciation.
Day 25-27: Ask Questions Instead of giving orders, ask questions that lead others to your desired conclusion.
Day 28-30: Make People Feel Important End every day by reflecting: “Did I make someone feel genuinely important today?”
How relevant are these principles nearly a century after they were written?

Cultural Shifts:
Despite these changes, human nature hasn’t fundamentally altered. We still:
This is why Dale Carnegie principles still work—they’re based on unchanging aspects of human psychology.
Be Genuine: Modern audiences detect insincerity quickly. Apply Dale Carnegie principles authentically, not manipulatively.
Use Technology Wisely: Send personalized video messages instead of generic emails. Remember digital interactions still involve real people.
Move at People’s Pace: While Dale Carnegie recommended patience, today’s fast pace requires balancing thoroughness with efficiency.
Respect Boundaries: Modern professionalism includes respecting personal space and time. Apply Dale Carnegie principles without being intrusive.
No system is perfect. Let’s honestly examine criticisms of Dale Carnegie’s work.
The Concern: Some view Dale Carnegie techniques as manipulation—flattering people to get what you want.
The Response: Dale Carnegie explicitly emphasized sincerity and genuineness throughout his work. The principles only work long-term when applied authentically. Manipulation is using techniques without genuine care for others; Dale Carnegie taught caring about others and expressing it effectively.
The Key Distinction: Intent matters. Using these principles to genuinely connect and create win-win outcomes is different from using them to exploit others.
The Concern: The book was written in 1936. How relevant can it be today?
The Response: While examples reference businesses and technologies from the 1930s, the underlying principles are timeless because human nature hasn’t changed. People still want to feel important, appreciated, and understood.
Modern Application: The principles work; the examples just need updating. Replace stories about telegraphs with emails, and the lessons remain powerful.
The Concern: The advice seems obvious—smile more, remember names, show interest. Everyone knows this.
The Response: Knowing and doing are different. Most people know they should exercise and eat well, but obesity rates prove knowing isn’t enough. Dale Carnegie provides not just principles but frameworks for consistent application.
The Reality: Simple doesn’t mean easy. Consistently applying these “obvious” principles is challenging and requires practice.
The Concern: Some people won’t respond to Dale Carnegie techniques no matter how well you apply them.
The Response: Dale Carnegie never claimed 100% success. However, improving your approach increases your success rate significantly. If techniques work 80% of the time instead of 50%, that’s massive improvement.
The Perspective: Focus on what you can control—your behavior—not others’ responses.
What impact has Dale Carnegie had on the world?
Global Reach:
Modern Programs: Dale Carnegie Training has expanded beyond the original course to include:
Dale Carnegie paved the way for an entire industry. Authors and speakers influenced by his work include:
Many modern self-help books essentially repackage Dale Carnegie principles with new examples and slight variations.
Phrases from Dale Carnegie’s work have entered common language:
His principles influence:
Theory means nothing without practice. Here are specific exercises to develop these skills.
Instructions: For 30 days, write down three people you genuinely appreciated each day and why. Then actually tell them.
Why It Works: This Dale Carnegie exercise trains your brain to notice positive things about others and builds the habit of expressing appreciation.
Progression: Start with easy targets (family, friends), then expand to coworkers, service workers, and even strangers.
Instructions: When meeting someone new, use their name three times in the first conversation. Repeat it immediately upon hearing it, use it mid-conversation, and use it when saying goodbye.
Why It Works: Repetition strengthens memory. This Dale Carnegie technique also makes the other person feel valued and helps them remember you.
Challenge: Try to remember and use names of five new people each week.
Instructions: In your next ten conversations, track your question-to-statement ratio. Aim for asking at least two questions for every statement about yourself.
Why It Works: This implements Dale Carnegie’s principle of showing genuine interest in others. People love talking about themselves, and asking questions makes you a better conversationalist.
Level Up: Practice asking follow-up questions that show you’re really listening, not just waiting your turn to talk.
Instructions: For one week, avoid all arguments. When someone disagrees with you, respond with “You might be right, I hadn’t thought of it that way.”
Why It Works: This Dale Carnegie principle teaches that winning arguments often costs you relationships. Avoiding arguments doesn’t mean abandoning your principles—it means choosing battles wisely.
Insight: Notice how many “arguments” are actually pointless disagreements about trivial matters.
Instructions: Smile at everyone you interact with for three full days. Note how people respond differently.
Why It Works: Dale Carnegie emphasized that a genuine smile is one of the most powerful tools for connection. Actions influence emotions—smiling actually makes you feel better too.
Observation: Track how many people smile back, how your mood changes, and whether interactions go more smoothly.
Dale Carnegie died in 1955, but his influence continues growing. His books have sold over 50 million copies combined, and Dale Carnegie Training continues teaching his principles to new generations.
What makes Dale Carnegie’s work endure? It’s not complex psychological theories or revolutionary insights into the human condition. It’s simple, practical wisdom about how to treat people that anyone can understand and apply.
The principles work because they’re based on fundamental human needs:
In our increasingly digital, isolated world, these needs are stronger than ever. Technology promised to connect us but often leaves us feeling more alone. Social media provides likes and followers but rarely deep relationships.
This is why Dale Carnegie principles matter more now than ever. They remind us that real connection happens through genuine interest, sincere appreciation, and treating others with dignity and respect.
You don’t need to take expensive courses or attend seminars to benefit from Dale Carnegie’s wisdom. Start with his books—especially “How to Win Friends and Influence People.” Read slowly. Take notes. Most importantly, apply one principle at a time.
Don’t try to implement everything at once. Choose one Dale Carnegie principle—maybe remembering names or giving sincere appreciation—and practice it consistently for 30 days. Once it becomes natural, add another.
Small changes compound. Improving your relationships by just 10% has massive ripple effects throughout your life—better opportunities at work, deeper friendships, more harmonious family relationships, and increased influence.
The question isn’t whether Dale Carnegie’s principles work. Millions of people across nearly a century have proven they do. The only question is whether you’ll apply them.
Knowledge without action is just entertainment. You now know the principles. The next step is yours. Pick one Dale Carnegie technique and use it today. Not tomorrow. Not after you finish reading. Today.
Because the person who applies even one principle consistently will achieve more than someone who knows all the principles but applies none.
Dale Carnegie understood something profound: success in life is overwhelmingly about how well you work with other people. Master that, and everything else becomes easier.
