It's a zero sum game. You only have so many hours in your life so valuing two things means you value each thing half as much as someone who values one thing.
Yes, and there's enough time for both - work is 35-40 hours, maybe some overtime if you're really dedicated. Even at 50 ( too much IMHO), with 54 for sleep (7x8), that still leaves you 68 for family.
Umm, yeah because nobody has chores to do. Cleaning, cooking, tidying, life admin, dealing with companies or people who are sucking away your time, home maintenance, etc etc
It doesn’t actually work that way - family can and will consume 100% of your time, just like work can. And some people can and will pick one of them and do just that.
If you’re ‘competitor’ is one of those people, well…..
