Even when you have doubts, take that step. Take chances. Mistakes are never a failure - they can be turned into wisdom.

Enjoy failure and learn from it. You can never learn from success.

Failure is not fatal, but failure to change might be.

Failure doesn't kill you... it increases your desire to make something happen.

Don't be afraid of missing opportunities. Behind every failure is an opportunity somebody wishes they had missed.

I don't believe in failure. It is not failure if you enjoyed the process.

You cannot climb the ladder of success dressed in the costume of failure.

Success is never final, failure is never fatal. It's courage that counts.

Failure is more frequently from want of energy than want of capital.

Failure is instructive. The person who really thinks learns quite as much from his failures as from his successes.
