Stress is good if you know how to address it.
Sometimes we might be overloaded with all the stress on our shoulders. Either there is no other person around who might help us or because we think we can deal with it.
As you can see optimal stress is the stress it helps you. That means you are using on your benefit.
I always perform better under stressful times than relaxed ones. Stress is giving me a chance to rethink everything in a short time of period. Then, I try to find a solution. If it is not under my control, I let it Go! I changed my perspective to stress instead of bad or killing me, I use it for my own good.
Pretty much it is your intention. If you believe that’s is good for you, you will get what you expected it.
