Dear original post author, you really need to start doing something that you enjoy or that motivates you. You can also try to structure your life in a way that allows you to not work when you don't feel like you can or will be efficient. This is one of the very reason I'm freelancing: I work when I want/can, and do not pretend the rest of the time. But when I'm working, I'm trying to stay as close as possible to 100%. I charge a premium rate for those very focused session, and do not pretend the rest of the time. There are times when I work a lot, a d times when I don't accept new projects because I need time off (usually 4 months a year)
I'm really wondering how healthy is, psychologically, all this pretending.
Anyway, I don't think you're alone in your situation but I don't think it's a good thing either
