Unfortunately, there seems to be far more opportunity out there than ability.... We should remember that good fortune often happens when opportunity meets with preparation.

I owe my success to the fact that I never had a clock in my workroom. Seventy-five of us worked twenty hours every day and slept only four hours - and thrived on it.

There cannot be overproduction of anything which men and women want. And their wants are unlimited, except by the size of their stomachs.

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.

The only thing I use my body for is to carry my brain around.

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.

There seems to be no limit to which some men will go to avoid the labor of thinking. Thinking is hard work.
