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