My main take away from what your are stating is that it doesn't matter whether you succeed or fail at something, it is whether you are running the engine too hot for too long.
Stop, breathe, relax, pace yourself.
One can burnout after a failure as quickly as after a success. However, one might want to get back on the stress train quicker with a success, since one expects a victory rush at the end of the stress which apparently made the stress worth it.
Yes, positive stress can cause it just as well. I had met the love of my life, traveled to Europe 7 times over a year, gotten married, moved to a foreign country I loved… and founded a new business. Life was pretty good.
