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

Things do not happen. Things are made to happen.

Quality is not an act, it is a habit.

If you think you can do it, you can.

The secret of getting ahead is getting started.

By failing to prepare, you are preparing to fail.

Be gentle to all and stern with yourself.

If you can dream it, you can do it.

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