Yeah I work in an FFRDC, pushing the frontier of our exploration of space. I'm quite passionate both about the employer and (most of the time) my work. If I didn't care about my employer at that level I woulda been out the door after two years. I think to myself sometimes about the other side of that though, like if I didn't care for them but the money was good.

My home hobbies resemble work within my area, but not my current job function, but I'm keenly aware my employer may try to take advantage of my other talents and do I guess the only thing that saves having an alternative hobby is that I'm so diversified that whatever my work task is I can work on an orthogonal hobby at home. It's kinda nice, I've got both really.

In my mind if I "sell out" (in terms of trading in for that sense of purpose in my work), and just work for the paycheck, then I would go for max. Work an HFT quant firm as a senior or principal engineer or research analyst. $$$. Or some other juicy gig. But I would hate myself if that became a slog and I had no time for my interests at home.
