"The starting point of all achievement is DESIRE. Keep this constantly in mind. Weak desire brings weak results, just as a small fire makes a small amount of heat."

"The only limitation is that which one sets up in one's own mind."

"A quitter never wins-and-a winner never quits."

"To win the big stakes in this changed world, you must catch the spirit of the great pioneers of the past, whose dreams have given to civilization all that it has of value, the spirit that serves as the life-blood of our own country – your opportunity and mine, to develop and market our talents."

"When defeat comes, accept it as a signal that your plans are not sound, rebuild those plans, and set sail once more toward your coveted goal."
