Maybe, maybe not. Directly, I only work about 30h/week, so I actually have 86 hours of free time and 30 hours of work per week.

And, at this point I'm working for my kids, not for me. I could have easily retired years ago if I didn't have kids. I could retire right now but my kids might not inherit much if I did. I lucked into a field that paid me > 10x the median salary in the US, but my kids might not be so lucky.

So, I'm working a little harder and longer than I need to, so that my kids perhaps don't have to. 1 year of working and saving for me might, 25 years from now, mean my kids can retire 10 years earlier than they would. That seems like a worthwhile thing for me to do, even if it means I have a little less "me" time.
