Believe and act as if it were impossible to fail.

Logic is an organized way to go wrong with confidence. We should all know by now that a logical course is not always the right one.

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

The world hates change yet it is the only thing that has brought progress.

Virtually nothing comes out right the first time. Failures repeated failures are finger posts on the road to achievement. The only time you don't want to fail is the last time you try something.... One fails forward toward success.

We need to teach a highly educated person that it is not a disgrace to fail and that he must analyze every failure to find its cause. He must learn how to fail intelligently for failing is one of the greatest arts of the world.

Keep on going and the chances are that you will stumble on something perhaps when you are least expecting it. I never heard of anyone ever stumbling on something sitting down.

It is easy to build a philosophy. It doesn't have to run.

A problem well stated is a problem half solved.

The faster you go the more chance there is of stubbing your toe but the more chance you have of getting somewhere.

No one would have crossed the ocean if he could have gotten off the ship in the storm.

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