I am about twice your age so my situation is a little different that yours. I'd be inclined to stick it out, because for $1M, I'd be able to retire. Granted it would be a modest retirement, but I could retire. Then I'd have time to work on what ever I wanted. Think about what you could do to improve your situation? Can you move to a different project? If it is something else bothering you a frank conversation with your manager may be helpful. I just did this myself today. I work for an early stage start-up and was ready to say fuck it and quit. I sat down with one of the founders and we discussed my grievances. I feel a lot better now, and I think it will be helpful in the long run. Also maybe you can do something outside of work to make things more meaningful. Take up a new hobby, or may a new side project.
