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

The greatest glory in living lies not in never falling, but in rising every time we fall.

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

Man and the animals are merely a passage and channel for food, a tomb for other animals, a haven for the dead, giving life by the death of others, a coffer full of corruption.

The most important thing in the life of every man and every woman is not that they should never fall along the way. The important thing is always to get back up, not to stay on the ground licking your wounds.

Show me a thoroughly satisfied man and I will show you a failure.
