I learned more about economics from one South Dakota dust storm than I did in all my years at college.

"If there is dissatisfaction with the status quo, good. If there is ferment, so much the better. If there is restlessness, I am pleased. Then let there be ideas, and hard thought, and hard work."

"Much of our American progress has been the product of the individual who had an idea; pursued it; fashioned it; tenaciously clung to it against all odds; and then produced it, sold it, and profited from it."

To err is human. To blame someone else is politics.

Never give up and never give in.
