The wise does at once what the fool does at last.
Never complain and never explain.
If you think you can do it, you can.
If you're going through hell, keep going.
Leap, and the net will appear.
Be thine own palace, or the world's thy jail.
Who seeks shall find.
I can, therefore I am.
By failing to prepare, you are preparing to fail.
Be gentle to all and stern with yourself.
A good teacher must be able to put himself in the place of those who find learning hard.
