One of my family members’ 12 year old son suddenly developed a health issue. His dad is worth at least 3M, and was looking to retire in his 40s. But the medical bills are insane, he can’t retire anytime soon, as most of the bills (tens of thousands a month) are being paid by the good insurance his employer gives him.
I have always spent much less than what I make (I don’t even have a bed, I happily sleep on the floor on a sleeping bag). But I also haven’t gotten any raise the last few years, while my rent (for the same apartment) has gone up 20% in the last 4 years. So has my other basic expense like phone bill (same phone, same carrier, same plan), internet etc.
There is a reason people spend long hours working because the alternative is worse.
The most sensible thing to do while one is young is to live frugally, but also earn as much as you can and save.
Then your life can be chaotic, messy, stressful, and you lose much freedom for many years! But on the plus side you learn to sacrifice everything you’ve done and earned for the good of children who don’t even know how to appreciate it!
Kids just happen to be the easiest way to force yourself to stop living for yourself.
