It's funny some of the things that stick with you through life. Little sayings, credos and whatnot. I still remember, from when I was a really little kid, a poem that accompanied an article about motorcyclist/daredevil Evel Knievel. It went "Never a horse couldn't be rode, never a rider couldn't be throwed". Yep, it's poor English, but it's pretty deep.
I learned a pretty good lesson from Billy Corgan of the Smashing Pumpkins too.
