I strongly disagree with this. I'm a compulsive person, I used to say yes to everything, I enjoy everything. I don't think I ever spent effort towards something that wasn't rewarding in some way or other.
However. Stress is stress and it can be negative or positive. Stress makes you perform better, adrenaline pumping, your senses sharpen. It can all be in a positive loop with great feedback, everyone loving what you do, amazing results, and still you end up burnt out.
My stress manifests physically, "skipped" heartbeats, adrenaline rushes when waking up in the night, I even got atricular fibrilation (AF) and was hospitalised to be "reset" through one of those heart machines you see in ER. I was convinced there was something very wrong with me. Heart problem? Doctors did test after test, and nothing.
I learnt my lesson, I know how to recognise the signs now. I can manage it by just taking care of myself.
But guess what, every single thing I do is fun, positive, great feedback.
