We suffer not from overproduction but from undercirculation. You have heard of technocracy. I wish I had those fellows for my competitors. I'd like to take the automobile it is said they predicted could be made now that would last fifty years. Even if never used, this automobile would not be worth anything except to a junkman in ten years, because of the changes in men's tastes and ideas. This desire for change is an inherent quality in human nature, so that the present generation must not try to crystallize the needs of the future ones.

here is a great difference between knowing a thing and understanding it. You can know a lot and not really understand anything.

Learn how to fail intelligently.

It is not a disgrace to fail. Failing is one of the greatest arts in the world.

What I believe is that, by proper effort, we make the future almost anything we want to make it.

It doesn't matter if you try and try and try again, and fail. It does matter if you try and fail, and fail to try again.

The price of progress is trouble.
