How to Deal With a Problem

It's easy to get into a rut in thinking. It is hard to shake yourself loose from one point of view and see and completely new. You tend to keep going back and repeating this same old kind of attack that has always failed. At such times it is best to close your book and work on something else or even if you can afford the time take a nap. When you come back to your problem the new approach may come to you in a flash  and from then on the work may go quickly and smoothly.
