Do not brood over your past mistakes and failures as this will only fill your mind with grief, regret and depression. Do not repeat them in the future.
Remember that failure is an event, not a person.
You cannot climb the ladder of success dressed in the costume of failure.
Failure is not fatal, but failure to change might be.
Failure is not a single, cataclysmic event. You don't fail overnight. Instead, failure is a few errors in judgement, repeated every day.
When I was young, I observed that nine out of ten things I did were failures. So I did ten times more work.
Success is the result of perfection, hard work, learning from failure, loyalty, and persistence.
Failure is a detour, not a dead-end street.
There is no failure except in no longer trying.
Failure should be our teacher, not our undertaker. Failure is delay, not defeat. It is a temporary detour, not a dead end. Failure is something we can avoid only by saying nothing, doing nothing, and being nothing.
