Failure is not a single, cataclysmic event. You don't fail overnight. Instead, failure is a few errors in judgment, repeated every day.
- Jim Rohn
Make failure your teacher, not your undertaker.
- Zig Ziglar
I am not discouraged, because every wrong attempt discarded is another step forward.
- Thomas A. Edison
You haven't failed until you quit trying.
Success is the proper utilization of failure.
