I tend to get jealous when I see people working with their hands, prefferably outside. Sometimes I even observe the guys cleaning the street and thinks, maybe its not that bad after all?
The times I have done such work (like construction) resulted in a much greater satisfaction and feeling in my body than after a day in front of the screen (even though I have been productive). Doing lots of running and gym but it does not generate the same feeling.
Have lately started to do something about it, maybe switch career totally.
