I play tennis twice a week and I inline skate twice a week (weather pending) and yesterday I commuted to and from work on inlines (first time I've done it, won't be the last, but won't be often).

Having such hobbies plus a couple of kids (now teenagers so they're somewhat less demanding of my time) means I just don't have the time to do extra hours if I'm going to get enough sleep.

And if I don't get enough sleep then the hours I do work are nowhere near as productive as those when I have had enough sleep.

Work fits around my personality. If that doesn't suit my employer, I find a new employer.

Caveats: I don't hunt the highest paying job. I'm never going to be enthusiastic enough to be chosen to lead - I've had minor management roles in the past, and they lead to, basically, being paid to either sleep less or spend less time as "not work me". Both of those options result in lower productivity.

I'm good enough at what I do to earn a living for the foreseeable future. That's good enough for me career-wise. For my physical and mental health, both of which are indicators of and contributory to happiness and longevity, I will continue to spend much of my non-working time playing tennis and inline skating and lifting weights so I can continue to do those things, that make me happy with life and the world, for as long as physically possible.

I tend not to the machine that consumes humanity, I tend to the machine that gives me my humanity.

Edited to add: I'll never be a rich man. But I will lead a rich life.
