It doesn't seem like it was always that way. At least, I've spent large amounts of time on a single project before. I do tend to get very unproductive during Summer.
1) Treat it as a disorder
I have Asperger's Syndrome.
2) Learn to live with less money, and find a way to not "work".
I plan on being a professional donor. I can live with less money. Unfortunately, there are others who will not live if I have less money.
Just because you're smart doesn't mean you have to do an intellectual job.
I have some resistance to doing a job like that. I think it's because I just want to create something. Somehow, this doesn't seem to do a lot to translate into me actually creating something.
Depending on the extent which you are willing to tamper with yourself to upregulate motivation, here are some things to look into:
adderall, ritalin, vyvanse, modafinil, nicotine, caffeine, piracetam, CDPCholine...
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?
