Everyone worries at one time or another. It is a part of our every day lives. We worry about deadlines, about financial problems, and about our relationships with others. Surprisingly, the fact is that worrying is not always a bad thing. Some amount of worry is necessary because it gives us time to concentrate on a problem and find possible solutions or ways to deal with it. Some worry is stimulating. It can propel you to do better work or to complete work on time. In other cases, however, our worries can interfere with our problem-solving abilities. We worry so much that it stops us from taking the steps needed to solve the problem. If it continues, worrying can take away our energy and lead to physical problems such as fatigue, headaches, muscle pain, and insomnia.
