Know or listen to those who know.

If you've got a talent, protect it.

If you think you can do it, you can.

Do not weep do not wax indignant. Understand.

Quality is not an act, it is a habit.

I can, therefore I am.

By failing to prepare, you are preparing to fail.

It's always too early to quit.

To know oneself, one should assert oneself.
