You can’t plan everything. I never planned to write books, it was not something I ever thought about. I thought I’d be a lawyer for the rest of my life. It’s important to have goals and to work hard for them, but life has a way of presenting opportunities that you don’t really notice at first. Success a lot of times depends on whether you make a change and try something that you hadn’t planned, something new. I give commencement speeches occasionally to colleges and high schools, and I usually dwell on that, tell the students, “Get your education and work hard, but don’t race toward the age of 22 or 23 when you’re out of college, and you’ve got the credit card, and you’ve got the BMW, and you want everything right then at the age of 23, because you’re not going to enjoy your education.” I tell kids to stay in school until they’re 30 years old. Their parents hate me for it, but nobody really takes you very seriously until you’re 30 anyway. You need to spend a lot of time in school.
