It is wild to me that people consider Dale Carnegie and Tony Robbins in the same boat. "How to Win Friends and Influence People" by Dale Carnegie completely changed how I communicate with people, for the better.

For nerds (like me) who think data and statistics are the way to persuade people, you're doing yourself a disservice by ignoring the truth. Lots of people think sales are icky, but much of life is influenced by your ability to persuade and sell, even yourself, to others.

the man leveraged the fact that his name was the same as Andrew Carnegie (having no relation) to launch a publishing empire. it was hacks from the beginning

Why is Tony Robbins a hack?
