Hard work brings prosperity; playing around brings poverty.

To bring one's self to a frame of mind and to the proper energy to accomplish things that require plain hard work continuously is the one big battle that everyone has. When this battle is won for all time, then everything is easy.

Hard work has made it easy. That is my secret. That is why I win.

I learned the value of hard work by working hard.

If the power to do hard work is not a skill, it's the best possible substitute for it.

Hard work is the key to success, so work diligently on any project you undertake. If you truly want to be successful, be prepared to give up your leisure time and work past 5 PM and on weekends. Also, have faith in yourself. If you come up with a new idea that you believe in, don't allow other people to discourage you from pursuing it.

It's true hard work never killed anybody, but I figure, why take the chance?

When I was a young man I observed that nine out of ten things I did were failures. I didn't want to be a failure, so I did ten times more work.
