As a young man, I was very interested in how people lived in earlier times; how they got from place to place, lighted their homes, cooked their meals and so on. So I went to the history books. Well, I could find out all about kings and presidents; but I could learn nothing of their everyday lives. So I decided that history is bunk.

Irrespective of whether you suspect you are able to do a factor or not, that you are right

Whether we think we can or cannot, we are right.

Every depression is a challenge to every manufacturer to put more brains into his business.

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.

I invented nothing new, I simply assembled the discoveries of other men behind whom there was centuries of work.

The gifted man bears his gifts into the world, not for his own benefit, but for the people among whom he is placed; for the gifts are not his, he himself is a gift to the community.
