Never give in--never, never, never, never, in nothing great or small, large or petty, never give in except to convictions of honour and good sense. Never yield to force; never yield to the apparently overwhelming might of the enemy.
Sir Winston Churchill, Speech, 1941, Harrow School

If your actions inspire others to dream more, learn more, do more and become more, you are a leader.
John Quincy Adams

Try not to become a man of success but a man of value.
Albert Einstein

Rely on your own strength of body and soul. Take for your star self-reliance, faith, honesty and industry. Don't take too much advice GÇö keep at the helm and steer your own ship, and remember that the great art of commanding is to take a fair share of the work. Fire above the mark you intend to hit. Energy, invincible determination with the right motive, are the levers that move the world.
Noah Porter
