I enjoy my work. It's what I'd be doing in my spare time if I didn't need or have this job. I've thought about this, and I think I'd stick around at my role even if I hit a windfall, because I want to see this through to the end, one way or another. Sometimes, in order to do the kind of job I would be proud of, I need to work very long hours. That's 100% fine with me, but it's not always been fine with some other people I work with.
I'll even go one step further; I like working with others who share this view on working. I know not everyone can do as I do, and not everyone wants to do as I do, but when I'm working with people who can and want to work long hours, I am substantially more satisfied at my job than when I work with 9-5ers.
I don't in any way begrudge those 9-5ers, I just would rather work with people who share my ability and desire to push as far as is needed to complete the work to a high standard that is usually not possible in 40 hours a week.
It just seems like I have to constantly kowtow to the 9-5ers because they get so bent out of shape when you suggest that their style of working is only one of many totally acceptable ways of living. "Work life balance!" they shout, but not all of us have bifurcated the concepts. Work and life don't have to be these entirely severed things, I much prefer to weave them together and work with other people who can weave them together successfully.
It's frustrating. There's some sort of moral nobility in "only" working 40 hours, like I'm the problem and they're just trying to live their lives. I don't mind! I just want to work with people who value the things I do.
