We have a lot of people revolutionizing the world because they've never had to present a working model.

One of the things we have to be thankful for is that we don't get as much government as we pay for.

Every great improvement has come after repeated failures. Virtually nothing comes out right the first time. Failures, repeated failures, are finger posts on the road to achievement. One fails forward toward success.

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

Nothing ever built arose to touch the skies unless some man dreamed that it should, some man believed that it could, and some man willed that it must.

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