It's always too early to quit.

The wise does at once what the fool does at last.

Things do not happen. Things are made to happen.

To know oneself, one should assert oneself.

If you think you can do it, you can.

If you can dream it, you can do it.

The dog that trots about finds a bone.

Expect problems and eat them for breakfast.

You never know what motivates you.
