I've been very, very successful at building probably the most recognizable, physically recognizable brand in personal development.

If life is no fun, it is because you are no fun. Your life is always a reflection of who you are... Try this: Stop taking things, including yourself, so seriously. Life is not as complicated as you have made it out to be.

I think one of the mistakes typically with authors is they have written more books than they've read.

I think you have to read a lot. I think if you're going to write about something you better have read at least 100 books on that topic.

When I'm writing a book - say I'm going to write a parenting book. I'll go out and buy the 100 top parenting books and I will read those, not so I can copy them for sure.

You can’t step up to the next level as long as you keep one foot on the lower level.

People hate the truth. Luckily, the truth does not care.
