There is no failure except in no longer trying.

The only guarantee for failure is to stop trying

Failure is the information you need to get where you’re going.

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

You fail only if you stop writing.

In reality, failure is simply feedback. It’s not that you are bad or not good enough or incapable. Failure (or feedback) gives you the opportunity to look at what’s not working and figure out how to make it work.

The only real failure is abandoning your principles. Killing what you love because you can’t bear to part from it is selfish and stupid. If your reputation can’t absorb a few blows, it wasn’t worth anything in the first place.

There is no failure. You win or you learn. Either one is okay.

A failure is not always a mistake. It may simply be the best one can do under the circumstances. The real mistake is to stop trying.

There is no such thing as failure, there's just giving up too soon.

In one world, failure is about having a setback. Getting a bad grade. Losing a tournament. Getting fired. Getting rejected. It means you’re not smart or talented. In the other world, failure is about not growing. Not reaching for the things you value. It means you’re not fulfilling your potential.

When the possibilities themselves had accordingly turned stale, when the secret of the gods had grown faint, had perhaps even quite evaporated, that, and that only, was failure. It wouldn’t have been failure to be bankrupt, dishonoured, pilloried, hanged; it was failure not to be anything.

One's only rival is one's own potentialities. One's only failure is failing to live up to one's own possibilities. In this sense, every man can be a king, and must therefore be treated like a king.

People automatically associate quitting with failure, but sometimes that's exactly what you should do. If you already spent too much time on something that wasn't worth it, walk away. You can't get that time back. The worst thing you can do now is waste even more time.
