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

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

Do not fear mistakes. You will know failure. Continue to reach out.

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

Do not let your ambitions become a sanctuary for your failures.

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

Success and failure are both part of life. Both are not permanent.

If you're not failing every now and again, it's a sign you're not doing anything very innovative.

Failure is simply a few errors in judgment, repeated every day.

Failure happens all the time. It happens every day in practice. What makes you better is how you react to it.
