I admit that the English teacher in me cringes at the grammar in this quote, but I think the message is a very good one, so I have left it intact rather than try to say it myself.
"If all your life you never do anything heavy, there’s certain passages in life that are heavy. Having a baby, for instance, is one. If you be a total paddy-@$$ all your life, they’re going to have to knock you out when you have your kid, because you’re going to be too chicken to have it. And if you do something that builds character ahead of time, you’ll have enough character that you can have that kid, and it will be a beautiful and spiritual experience for you."
