I think it's a delicate balance that you have to strike between a career and a life. Where I work it's pretty obvious that a lot of people don't get that. I know a lot of people who work 12 hour days average, often coming in on the weekends. These are people who are married with kids. It kinda makes me sad.
I think you just have to find a place that fits though. If that's not a career-oriented job then that's great. But it's also nice to have some stability too. With how things have been, it's good to even start thinking about retirement in your 20s - how much to save, what kind of retirement fund, all that. With pensions pretty much being killed by the 401k and social security being a total wreck retirement funding isn't guaranteed by anything but your bootstraps (thanks, republicans). Plus there's the cost of healthcare, which is absolutely absurd, and hospitals/insurers are justifying inflating their costs because of Obamacare even though really they could just cut their billion-dollar profit margins by a small percent to offset it. (If you want to be seriously depressed, read this. It was just poor timing that I read that after having $3000 in testing done with none of the cost being discussed with me prior).
I don't know why I'm rambling about this so much, I think it's just because it's a lot of stuff I'm actively thinking about. It's a pretty hard balance to strike overall, between having fun and playing the long game; it's really unwise to be consumed too much by either. Okay I'm done brain dumping.
