Stress is good or bad, what you think. I think both. There is common saying. Excess of everything is bad. So overdose create problem.
Why Stress is good. Stress means caring. You are taking care of something. That will happen or require to happen. You put efforts and now result will come. or you take stress that I have to do something with care. If I am unable to do things what will happen. If I deliver something, It will properly deliver it.
But same time it will become bad if it is become habit. We start to busy as habit. For example overstress boiled our blood, problem of high blood pressure and heart attack. All these things result of taking stress.
Best way to take only tension of those things which we can control or which we can not control.
What other thinks about us, that is beyond our control. Why we stress.
but what we can improve, that need stress. Things we do with care, that need stress.
If we want to control stress. We need to focus on what we are thinking. Thought trigger stress. We can not control thought but we forcefully.
