Don't worry about a thing, 'Cos every little thing is gonna be alright.

I never worry about action, but only about inaction.

The reason why worry kills more people than work is that more people worry than work.

Worrying is like paying a debt you don't owe.

It's time we stop worrying, and get angry you know? But not angry and pick up a gun, but angry and open our minds.

You can destroy your now by worrying about tomorrow.
