Usually its the extremes that are having the same effects.
Atm I am in a super demanding job, requiring me to overwork, make decisions on the spot, work on problems etc.
On my free time while I want to sit down and watch some TV, go for running, enjoy a nice dinner or whatever... I FEEL EMPTY!
I am fixated with my work... its not healthy and its creating low motivation for me. It feels like work has taken away all pleasures in life for me. It is not HEALTHY at all (I am currently seeing professionals about it)
Generally anything in moderation is key...
P.S. I do overwork myself for someone else to enjoy the fruits of my labour... sad story.
