1) okay, I'm fascinated by the 'fighting in a foreign civil war' thing, can you expound on that?

2) this may sound weird, but I do think that if you want to be a good parent (and please note, I don't actually have kids yet, so ignore this advice if it doesn't ring true) is finding ways to get your 'alone' time despite family responsibilities. I'm also an introvert, but my 'recharge' time is stuff like meditation and solo-programming and math time, so that's pretty easy to do, just set aside a few hours a day to recharge my batteries so I can be fully present for my family the rest of the time, I can see that fighting in a foreign civil war isn't exactly the type of thing you can fit into an hour in the morning before the kids wake up, but if you have similar introverted activities that recharge you that can be more easily done alongside family life, I would argue that you'll be doing your family a disservice not to do them- they deserve you at your best, which means you should give yourself time do fully recharge yourself so you can be there for them the rest of the time.

I am on point, about 1.3% of the year, being a father, husband.

That 1.3% or about 5 days is my vacation.

I went' from ~60% free time to 1% and I wouldn't trade it for anything.
