Oh that's cool that you came here through MMM forums! I was hoping that people would find Steemit as it can be quite interesting here (after you find people that post things you like).
Yeah, as an INFP you are near the bottom of the list. I would imagine that a lot of the people around you are spendypants. You must have great willpower to give up spending, but as you see it is VERY worthwhile.
I don't make all that much either as my family is single income and two kids, but since we are FIRE focused our networth has increased dramatically with barely any increased income from work. Side hustles and frugality can really make up the difference.
I also think those with big incomes get somewhat complacent because of it. A sort of financial tortoise and the hare situation.
Thanks for checking Steemit out and try to stick around - it has been worth it to me!
