WHAT DO YOU KNOW NOW THAT YOU DIDN'T KNOW IN YOUR '20s and 30s?
DAVID HASSELHOFF, star of "Piranha 33DD, "Baywatch" alum and cultural icon.
"Here is what I know now that I didn't know then:
Life is not fair. So get over it.
Get on with it.
When you least expect it life will come up and bite you in the butt.
Still....You have to laugh at yourself.
Laugh at your mistakes.
Don't listen to what people say about you.
Listen to yourself.
Keep a positive attitude.
And always remember this:
Life is waiting for you.
It's yours to screw up."
