When you start working on changing your perception of other stressors, the same things happen. Instead of debilitating influence, you build your resistance, improve stress response, and get motivated with the event. You learn how to channel this energy boost the initial adrenalin, and cortisol spikes give you – use it for your advantage to help you create or act.
This good stress was named Eustress by Hans Selye, the same scientist who discovered General Adaptation Syndrome. Eustress can be biochemical in nature, psychological or physical, but regardless of where it comes from, it works in the same way and is actually very helpful. Some of the benefits that Eustress brings are, among others focus, motivation, alertness, excitement, and more, all of which help us perform better.
