These tests are very popular. They let you know in a matter of minutes how to settle a question that keeps nagging you, how to understand a subject that intrigues you, how to avoid jumping off in the wrong direction, how to make a catastrophic decision and, above all, how to know which way you should go or how to find a solution to your dilemma.

The trouble with tests is that they can oversimplify, so keep the results in perspective. A test is only a tool for you to use. Don't let yourself be used by the tool.
