"They say only two things are certain: death and taxes. I say there's three: death, taxes, and when you're in a hurry, there's always some old guy in front of you driving 20 miles under the speed limit…"

"I used to think the worst thing in life was to end up all alone. It's not. The worst thing in life is to end up with people that make you feel all alone."

"I think the saddest people always try their hardest to make people happy because they know what it's like to feel absolutely worthless and they don't want anyone else to feel like that."

"The only thing I ever learned in school was that if you want to be popular, you have to be funny."

"I'm a big fan of being kind to others. I think it's the most important thing."
