I can, therefore I am.

To know oneself, one should assert oneself.

The dog that trots about finds a bone.

Expect problems and eat them for breakfast.

Things do not happen. Things are made to happen.

Without hard work, nothing grows but weeds.

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

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

You never know what motivates you.
