Things do not happen. Things are made to happen.

Expect problems and eat them for breakfast.

Quality is not an act, it is a habit.

Be gentle to all and stern with yourself.

By failing to prepare, you are preparing to fail.

If you think you can do it, you can.

Without hard work, nothing grows but weeds.

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

Know or listen to those who know.
