Start where you are, with what you have. Make something of it and never be satisfied.

There is no shortcut to achievement.

Since new developments are the products of a creative mind, we must therefore stimulate and encourage that type of mind in every way possible.

Young people, I want to beg of you always keep your eyes open to what Mother Nature has to teach you. By so doing you will learn many valuable things every day of your life.

One reason I never patent my products is that if I did it would take so much time, I would get nothing else done. But mainly I don't want my discoveries to benefit specific favored persons.

All my life I have risen regularly at four o'clock and have gone into the woods and talked to God. There He gives me my orders for the day.

Anything will give up its secrets if you love it enough.
