It's always too early to quit.

After a storm comes a calm.

Go for it now. The future is promised to no one.

To know oneself, one should assert oneself.

The most effective way to do it, is to do it.

By failing to prepare, you are preparing to fail.

Well done is better than well said.

To be a good loser is to learn how to win.

The dog that trots about finds a bone.
