I never view mistakes as failures. They are simply opportunities to find out what doesn't work.

Each time you fail, you have eliminated another wrong option.

A failure teaches you that something can't be done-that way.

I have not failed. I've just found 10,000 ways that won't work.

Many of life's failures are people who did not realize how close they were to success when they gave up.

Failure is an option here. If things are not failing, you are not innovating enough.
