Don't be afraid to stumble. Any inventor will tell you that you don't follow a plan far before you strike a snag. If, out of 100 ideas you get one that works, it's enough.

Obsolescence is a factor which says that the new thing I bring you is worth more than the unused value of the old thing.

Research is an organized method for keeping you reasonably dissatisfied with what you have.

Research is industrial prospecting. The oil prospectors use every scientific means to find new paying wells. Oil is found by each one of a number of methods. My own group of men are prospecting in a different field, using every possible scientific means. We believe there are still things left to be discovered. We have only stumbled upon a few barrels of physical laws from the great pool of knowledge. Some day we are going to hit a gusher.

We work day after day, not to finish things; but to make the future better ... because we will spend the rest of our lives there.
