I can, therefore I am.

Things do not happen. Things are made to happen.

If you can dream it, you can do it.

Be gentle to all and stern with yourself.

Always desire to learn something useful.

Do not weep do not wax indignant. Understand.

Quality is not an act, it is a habit.

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

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