I've never made a mistake. I've only learned from experience.

Some mistakes will be made along the way. That's good. Because some decisions are being made along the way. We'll find the mistakes. We'll fix them.

There is great value in disaster. All our mistakes are burned up. Thank God we can start a new.

The only real mistake is the one which we learn nothing.

It's good to learn from your mistakes. It's better to learn from other people's mistakes.

To rectify past blunders is impossible, but we might profit by the experience of them.
