If you think you can do it, you can.

To know oneself, one should assert oneself.

The dog that trots about finds a bone.

Expect problems and eat them for breakfast.

Know or listen to those who know.

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

Be thine own palace, or the world's thy jail.

If you're going through hell, keep going.

Well done is better than well said.
