Billy Wilder

If you're going to tell people the truth, be funny or they'll kill you.

Trust your own instinct. Your mistakes might as well be your own, instead of someone else's.

Of course, there must be subtleties. Just make sure you make them obvious.

You have to have a dream so you can get up in the morning.

One day it happens. Success happens and it catches you by surprise. One day you are a signature, next day, you are an autograph.

Hindsight is always twenty-twenty.
