The first rule of discovery is to have brains and good luck. The second rule of discovery is to sit tight and wait till you get a bright idea.

It is better to solve one problem five different ways, than to solve five problems one way.
A great discovery solves a great problem, but there is a grain of discovery in the solution of any problem. Your problem may be modest, but if it challenges your curiosity and brings into play your inventive faculties, and if you solve it by your own means, you may experience the tension and enjoy the triumph of discovery.
Solving problems is a practical art, like swimming, or skiing, or playing the piano: you can learn it only by imitation and practice.
Solving problems is a practical skill like, let us say, swimming. We acquire any practical skill by imitation and practice. Trying to swim, you imitate what other people do with their hands and feet to keep their heads above water, and, finally, you learn to swim by practicing swimming. Trying to solve problems, you have to observe and to imitate what other people do when solving problems, and, finally, you learn to do problems by doing them.

Some of those kids, when they were old enough, would go out and shine shoes. They would show up at the gate of our compound to shine shoes, and you'd swear they were looking for their fathers.
