         Stress is a dynamic condition in which an individual is confronted with an opportunity, constraint, or demand related to what he or she desires and for which the outcome is perceived to be both uncertain and important. This is a complicated definition. Let's look at its components more closely. 
         Stress is not necessarily bad in and of itself. While stress is typically discussed in a negative context, it also has positive value. It is an opportunity when it offers potential gain. Consider, for example, the superior performance that an athlete or stage performer gives in "clutch" situations. Such individuals often use stress positively to rise to the occasion and perform at or near their maximum. 
          More typically, stress is associated with constraints and demands. The former prevent you from doing what you desire. The latter refers to the loss of something desired. So when you take a test at school or you undergo your annual performance review at work, you feel stress because you confront opportunities, constraints, and demands. A good performance review may lead to a promotion, greater responsibilities, and a higher salary. But a poor review may prevent you from getting the promotion. An extremely poor review might even result in your being fired. 
           Two conditions are necessary for potential stress to become actual stress. There must be uncertainty over the outcome and the outcome must be important. Regardless of the conditions, it is only when there is doubt or uncertainty regarding whether the opportunity will be seized, the constraint - removed, or the loss avoided that there is stress. That is, stress is highest for those individuals who perceive that they are uncertain as to whether they will win or lose and lowest for those individuals who think that winning or losing is a certainty. But importance is also critical. If winning or losing is an unimportant outcome, there is no stress. If keeping your job or earning a promotion doesn't hold any importance to you, you have no reason to feel stress over having to undergo a performance review.
