When you get a whole country - as did ours - thinking that Washington is a sort of heaven and behind its clouds dwell omniscience and omnipotence, you are educating that country into a dependent state of mind which augers ill for the future.

The time is coming when man will be able to determine the length of his lifespan by controlling his diet.

The whole key of the profitable everyday living will be to discover out what's one's future to try and do, and after that do it.

If you don't think of the future, you won't have one.

Thinking is the hardest work there is, which is probably the reason why so few engage in it.

The short successes that can be gained in a brief time and without difficulty, are not worth much.

You can do anything if you have enthusiasm. Enthusiasm is the yeast that makes your hopes rise to the stars. Enthusiasm is the spark in your eye, the swing in your gait, the grip of your hand, the irresistible surge of your will and your energy to execute your ideas. Enthusiasts are fighters, they have fortitude, they have strong qualities. Enthusiasm is at the bottom of all progress. With it there is accomplishment. Without it there are only alibis.
