What Does Pressure Do to Us
In modern society people are faced with fierce competition, and the pressure has become greater than ever before.
In the last few years quite a number of men and women have chosen "downshifting": do something less competitive. They decide to trade their highly-paid but also highly demanding position for a not-so-well-paid but a less challenging one. They are afraid that the stresses and strains of work will rob them of joy and happiness and do them harm both physically and mentally.
In fact, stress isn’t the bad thing it is often supposed to be, unless it gets out of control. Certain amount of stress is vital to providing motivation and challenge, and giving purpose and significance to an otherwise meaningless, idle life. People under stress tend to express their flail range of potential and to actualize their own personal worth--the very aim of a human life.
