Know or listen to those who know.

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

If you're going through hell, keep going.

Begin to be now what you will be hereafter.

Things do not happen. Things are made to happen.

The dog that trots about finds a bone.

Expect problems and eat them for breakfast.

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

To know oneself, one should assert oneself.
