One would have to be a fool to overlook the importance of using positive thinking for you rather than knowing negative thinking to work against you. In recent years, research in psychopharmacology （精神药理学） has proved what many people have known over the centuries: a positive attitude is good for you, good for your health, good for your wealth, good for everything.
Researchers have found that a positive attitude produces a specific chemical reaction which makes people feel better, while negative thinking results in a reduction of hormone（荷尔蒙） and shuts down the immune system. This leads to illness and depression. Positive thoughts will make you feel better. Even if you must begin by forcing yourself to be positive, it will become contagious and the positive thoughts will produce nice little chemicals and good feelings which will reinforce the positive thoughts.
For example, if you force yourself to smile or laugh, even when you dont feel like smiling or laughing, if you keep at it for a few minutes, you will soon feel like it. Feelings can make thoughts alive, and thoughts can do it, too. Control your thoughts and you can control your feelings. Positive thinking is important in all aspects of our lives. There is probably no single factor more important in determining your success in achieving your career purposes than your own attitude.
Its often been said that in the land of the blind, the oneeyed man is king. And in the office of militant（好战的） negativism, the positive workers shine like gold. You cannot control external events, but you can learn to control your reaction to those events and thereby have a positive attitude and be happy. This important key to success is totally within your control. Use it.
