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

Never mistake activity for achievement.

It isn't what you do, but how you do it.

It's not so important who starts the game but who finishes it.

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

Anyone who attempts is not a failure. Sarah Dessen

Losers quit when they fail. Winners fail until they succeed.

"Anyone who stops learning is old, whether at twenty or eighty."

Mistakes are the portals of discovery.

Don’t worry about failures, worry about the chances you miss when you don’t even try.

You should become a connoisseur of your own mistakes, turning them over in your mind as if they were works of art, which in a way they are.

Failure is an attitude, not an outcome.

First principle: never to let one’s self be beaten down by persons or by events.

In any case, you must not confuse a single failure with a final defeat.

It is impossible to live without failing at something, unless you live so cautiously that you might as well not have lived at all – in which case, you fail by default.

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.

Negative results are just what I want. They’re just as valuable to me as positive results. I can never find the thing that does the job best until I find the ones that don’t.

I can accept failure, everyone fails at something. But I can’t accept not trying.

Life is to be lived, not controlled; and humanity is won by continuing to play in face of certain defeat.

Failure is unimportant. It takes courage to make a fool of yourself.

I have not failed. I’ve just found 10,000 ways that won’t work.

Sometimes life’s going to hit you in the head with a brick. Don’t lose faith. 

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.

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.

Victory has a hundred fathers, but failure is an orphan.

When you fail to prepare, you’re preparing to fail.

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

Science, my lad, is made up of mistakes, but they are mistakes which it is useful to make, because they lead little by little to the truth.

We are all full of weakness and errors; let us mutually pardon each other our follies.

The only failures are those who fail to try.

"Aromatic plants bestow no spicy fragrance while they grow; but crush'd or trodden to the ground, diffuse their balmy sweets around."

Failure is success if we learn from it.

The best way out is always through.

Without failure there is no achievement.

The cost of failure is…learning.

To err is human, to forgive, divine.

No man is a failure who is enjoying life.
