This is for a variety of reasons. First, rushing means that we are much more likely to make mistakes – and, at times, those mistakes can have major consequences. Consider, for example, when you have made a mistake or you have been on the receiving end of someone else’s mistake. How often did the mistake arise because the person concerned was rushing, not paying sufficient attention to what they were doing?
Second, one of the key factors in stress is control. People can generally cope with a high level of pressure, provided that they have sufficient control over the demands being made on them, while even a relatively modest amount of pressure can produce a stress reaction if control is lacking. Rushing takes away our sense of control; when we are rushing, we tend to feel that we are losing our grip, that control is slipping away from us.
