I can, therefore I am.

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

Be gentle to all and stern with yourself.

Be kind whenever possible. It is always possible.

Things do not happen. Things are made to happen.

Quality is not an act, it is a habit.

If you're going through hell, keep going.

If you think you can do it, you can.

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