Ultimately, we all have to decide for ourselves what constitutes failure. But the world is quite eager to give you a set of criteria if you let it.

Failure will never overtake me if my determination to succeed is strong enough.

You can’t let your failures define you. You have to let your failures teach you.

Success depends upon previous preparation, and without such preparation there is sure to be failure.

When it’s tough, will you give up or will you be relentless?

I’ve missed more than 9000 shots in my career. I’ve lost almost 300 games. 26 times, I’ve been trusted to take the game winning shot and missed. I’ve failed over and over and over again in my life. And that is why I succeed.

You have to be able to accept failure to get better.

Anyone who has never made a mistake has never tried anything new.

Failure is an importance part of your growth… Don’t be afraid to fail.

Making your mark on the world is hard. If it were easy, everybody would do it. But it’s not. It takes patience, it takes commitment, and it comes with plenty of failure along the way.

In a world that’s changing really quickly, the only strategy that is guaranteed to fail is to not taking risks.

If you set your goals ridiculously high and it’s a failure, you will fail above everyone else’s success.

Please know that I am aware of the hazards. I want to do it because I want to do it. Women must try to do things as men have tried. When they fail, their failure must be a challenge to others.

It is hard to fail, but it is worse never to have tried to succeed.

Success is stumbling from failure to failure with no loss of enthusiasm.

The only real failure in life is not to be true to the best one knows. 

My great concern is not whether you have failed, but whether you are content with your failure.

The only failures are those who fail to try.

You always pass failure on the way to success.

You make mistakes. Mistakes don’t make you.

Failure is a detour, not a dead-end street.

Not failure, but low aim, is a crime.

Failure either ruins you or turns you into the man you can become.
