Man knows so much and does so little.

Do not be afraid of mistakes, providing you do not make the same one twice.

Great services are not canceled by one act or by one single error.

Failure is an event not a person

Failure is the foundation of success, and the means by which it is achieved.

To stumble twice against the same stone is a proverbial disgrace.

If something's important enough, you should try. Even if you - the probable outcome is failure.

A person should not be too honest. Straight trees are cut first and honest people are screwed first.

Failure cannot cope with persistence.

The errors of great men are venerable because they are more fruitful than the truths of little men.

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

You have committed a double mistake, firstly by not keeping the engagement yesterday and secondly, by coming when you were not expected.

As soon as the fear approaches near, attack and destroy it.

You will soon break the bow if you keep it always stretched.

At fifteen life had taught me undeniably that surrender, in its place, was as honorable as resistance, especially if one had no choice.

Many of life's failures are people who did not realize how close they were to success when they gave up.

Failure is simply an opportunity to begin again, this time more intelligently.

Any man can make mistakes, but only an idiot persists in his error.

The fire that warms us can also consume us; it is not the fault of the fire.

One of the most common causes of failure is the habit of quitting when one is overtaken by temporary defeat.

Failure is not a single, cataclysmic event. You don't fail overnight. Instead, failure is a few errors in judgement, repeated every day.
