To add to the other comments. That is not how everyone is wired. Some good friends of mine give everything at work and often have trouble to stop thinking about work afterwards. These people worked in shitty private sector jobs, governmental positions and other career paths that will never reward their work with richness.

I personally don't get it. It actually frustrates me a little, they are talented and could achieve real wealth if they'd cared for that. But I accept that people who just work 100% no matter what exist.
