Plan B. You've always got to have a Plan B.

Boxing is a great exercise ... as long as you can yell "cut" whenever you want to.

The problem is, your ego sometimes tells you that you can do many things. But sometimes it's best to stay focused and be honest with yourself.

I started out as an actor, but I forced myself to be a writer, even though I wasn't very good at it and had never written. I don't think I ever passed an English course in my life. My first eight to 10 scripts were pretty horrendous, but I stayed at it, stayed at it, and stayed at it, until I eventually found a voice and a subject like Rocky that people were interested in.

I keep trying to tell people. I said, at 40, 45, you're at that crossroads. You really are there. And it's not like you can have gain without pain, but this is it. The days are - like when I wrote this whole thing about, in the beginning of my first magazine. I said, "If you live to be 75 years old, that's 3,900 weekends. That's it."

Every champion was once a contender that refused to give up.

I know I can't play funny roles in movies. I tried, and it didn't work.
