Well then do something you enjoy that's not productive right now, but can become so if you try enough to raise your skill at it. Every ability I can boast of so far has been picked up along the way as I was avoiding tasks I ought to have worked on in favor of leisure activities that still required some sort of skill to be performed well. Even procrastination can be useful if your chosen method of procrastinating earns you abilities for which someone, somewhere is willing to pay you.
That is, as long as you don't refuse to enjoy something on the grounds that it might turn out to be lucrative one day, and therefore it's not proper enjoyment.
It's not that I'm not skilled at the things I like. It's that the stuff I want to do is stuff like reading and playing videogames. It's not something you can feasibly make a living doing. Also, I'm pretty sure that the few actual jobs there are in areas like that still end up pretty unpleasant.
I have a master's project I'm having trouble working on. It's something I've wanted to do, and I even started working on, long before I started my master's degree. If I can't even enjoy that, then I'm doomed to spend eight hours a day doing something I hate for the rest of my life. Even if I manage to improve my willpower, I doubt I'll be very productive doing something I don't want to do.
Does anyone have any idea how I can enjoy working more?
