One way to learn is from your own experiences.
But another way to learn is from other people's experiences.
See, one book might save you 5 years if you read it. Did you known, there's books on how to be stronger? More decisive? Be a speaker? Be a leader? Have a better effect on other people? Develop your personality? Did you known there's books on that and people don't read them. ? Did you known that hundreds of successful people have written their stories in books, and they wrote down how they did it,
and people dont't read it? How would you explain that?
