I can, therefore I am.

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

Know or listen to those who know.

If you've got a talent, protect it.

Without hard work, nothing grows but weeds.

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

By failing to prepare, you are preparing to fail.

Leap, and the net will appear.

Quality is not an act, it is a habit.
