Failures are finger posts on the road to achievement.

Business

If a fellow wants to be a nobody in the business world, let him neglect sending the mail man to somebody on his behalf.

Failure

Believe and act as if it were impossible to fail.

Future

My interest is in the future because I am going to spend the rest of my life there.

Invention and Inventor

An inventor is simply a person who doesn't take his education too seriously. You see, from the time a person is six years old until he graduates form college he has to take three or four examinations a year. If he flunks once, he is out. But an inventor is almost always failing. He tries and fails maybe a thousand times. It he succeeds once then he's in. These two things are diametrically opposite. We often say that the biggest job we have is to teach a newly hired employee how to fail intelligently. We have to train him to experiment over and over and to keep on trying and failing until he learns what will work.

Problems

Problems are the price of progress. Don't bring me anything but trouble. Good news weakens me.

Understanding

There is a great difference between knowing and understanding: you can know a lot about something and not really understand it.
