Well, imo, it's all important. I mean..it's his passion that set him apart. One of my favorite quotes ever...and not even because it's from Woody...but it's...
"I've had smarter people around me all my life, but I haven't run into one yet that can outwork me. And if they can't outwork you, then smarts aren't going to do them much good. That's just the way it is. And if you believe that and live by it, you'd be surprised at how much fun you can have.”
There's also the story about him going to Vietnam to visit troops. Where he stopped in to talk to the Ohio boys in the hospital. He promised one guy he'd visit his family back home and deliver a letter and let them know their son was ok. It's the good and the bad that made up Woody. The bad was well known, because it happened in public...but he still didn't go around telling everyone the good he had done. That, imo, is what made him a great man.
