I can, therefore I am.

Know or listen to those who know.

Do not weep do not wax indignant. Understand.

The dog that trots about finds a bone.

Things do not happen. Things are made to happen.

To know oneself, one should assert oneself.

If you've got a talent, protect it.

If you're going through hell, keep going.

If you think you can do it, you can.
