Nike is right. So was my father. Just do it.

When I was 24 years old, I discussed a business idea with my father. I asked him if he thought I should try it. He said he didn’t know if I’d succeed, but he did know that if I didn’t try it, for the rest of my life I’d wonder what would have happened if I did try it.

If you wonder what will happen if you write and publish a book—try it! The risk is low and the potential benefit is huge.

Words are toys for me. As a writer, I get paid to have fun. Writing books and blogs is probably the second best way for a man to make money. I'm 66, so I have little chance of employment as a gigolo. (Anyway, wife Marilyn has an exclusive contract for my intimate services.)

If I can publish books, so can others. (And, of course, my books can help.)

There's no reason to wait until next year, next week or tomorrow to start a book. Just do it -- NOW.

Be productive. Have fun. Be useful. Be innovative. Don't be afraid to piss people off. What you think of yourself is more important than what others think of you. Write to please yourself. It's nice if your words cause others to smile, say "thanks" and pay money; but self-satisfaction is more important. Not everyone has to "get" you. Even a small happy audience can be satisfying.

Don't leave the keyboard until you're staisfied with what you've written, because you never know which words will be your last words.
