Know or listen to those who know.

The dog that trots about finds a bone.

If you think you can do it, you can.

Who seeks shall find.

If you've got a talent, protect it.

To know oneself, one should assert oneself.

By failing to prepare, you are preparing to fail.

Do not weep do not wax indignant. Understand.

Quality is not an act, it is a habit.
