Fat s should no longer feel guilty about leaving a little food on the plate, a successful businessman need not feel guilty about spending a little too much money on a vacation, nor should he feel guilty that he can combine a business trip to the West Coast with some swimming and golf at an ocean resort. But many people do feel guilty over such apparently innocent actions. Excessive guilt can sour all of life and make life not worth living; it can also cause self-hatred as well as other fears and anxieties that cause all life's successes to be bittersweet, at best.

Stress from physical activity, if not carried too far, is actually beneficial. Exercise relaxes you and may help forget about mental and emotional stress. But mental stress is almost always bad for you. If mental stress is unrelieved, it can actually cause diseases such as ulcers, migraine headaches, heart problems, or mental illness.

Just as we need a little guilt—to keep us correct—and a little worry—to make us plan ahead—we need a little stress to stay interested in life. But when stress begins to bother you, you might as well change your routine. Take your mind off your worries with some physical activity; you may discover a solution you have overlooked before.

Stress is a natural part of everyday life and there is no way to avoid it. In fact, it is not the bad thing it is often supposed to be. A certain amount of stress is vital to provide motivation and give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.

Some people are not afraid of stress, and such characters are obviously prime material for managerial responsibilities, others lose heart at the first signs of unusual difficulties.

In the first stage, your body prepares to meet the stress. The heartbeat and respiration rates increase, and the pupils of the eyes dilate; the blood sugar level increases, and the rate of perspiration speeds up, while digestion slows down as blood and muscular activity is diverted elsewhere. In the second stage, your body returns to normal and repairs any damage caused by the stressful situation. However, if stress continues, the body cannot repair itself, and the final stage, exhaustion, then begins. If this stage continues, if for example you are frustrated by your work and continue to be frustrated for
