You've been around for a while. You've had you're ups, you've had your downs. And there's probably one thing you understand better than anyone else that you can wrap up in a sentence or two.
Share it with the rest of us. Don't feel like you need to expound upon the profundity of what you have to say. We'll take it for granted.
If you have a conscience you're always a better person than you think you are.
