“Work Life Balance” is missing and item—Career. I don’t think it should be that hard to find the right balance between all three, and you should especially try to have career bleed into work more than life. But if you have any aspirations of getting promoted to a high level and making lots of money (I’m not saying you should have those aspirations), then it’s very likely you’ll need devote at least some of your free time to gaining skills and knowledge that will help you grow in your career.
