Ideas without execution are hallucinations.

The only time I really become discouraged is when I think of all the things I would like to do and the little time I have in which to do them.

Opportunity is missed by most people because it is dressed in overalls and looks like work.

What is a college? An institute of learning. What is a business? An institute of learning. Life, itself, is an institute of learning.

There is no subsitute for hard work.

Today, I am wondering what would have happened to me by now, if, fifty years ago, some fluent talker had converted me to the theory of the eight-hour day and convinced me that it was not fair to my fellow-workers to put forth my best efforts in my work? I am glad that the eight-hour day had not been invented when I was a young man. If my life had been made up of eight-hour days, I don't believe I could have accomplished a great deal.

I have not failed. I've just found 10,000 ways that won't work.
