The rat - race can be a ringer. It's only worth doing if you legitimately enjoy your work. The money alone will not sustain you for 80+ hour workweeks in the long run. At least that's the conclusion I came to at appx age 30 when I jumped off the fast track in favor of more free time. I will say this w/r/t time with your kids-- the most important things you can give them are a) their lives to begin with and b) a materially safe existence and c) love. When those are in place, they have the ability to achieve their potential. Quality time with the parents is nice, but overrated in the grand scheme of things. They will remember the high points, and your personal qualities, not the quantity of time you spend with them. My parents ate shit, figuratively, so I could enter adulthood on a better trajectory than they did, and I consider that more loving than attending all my little league games. Life is full of tradeoffs. That's what makes things interesting.
