If you think you can do it, you can.

By failing to prepare, you are preparing to fail.

If you can dream it, you can do it.

The dog that trots about finds a bone.

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

After a storm comes a calm.

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

To know oneself, one should assert oneself.

It's always too early to quit.
