While I probably don't earn as much as OP, when I compare myself to my friends, I earn more than most and still spend less, living on about half my income too. Main differences in lifestyle are I don't buy shit (I don't even shop online at all most of the time so no temptation, when I consider buying an item I ask myself "do i really need this" and most often find that I don't, I try to get most items from nearby businesses, I don't subscribe to stuff may it be paying services or even newsletters, hell I even found half of my furniture on the streets or second hand), I cook like 90% of my meals (takeaway is an extra 2-3 times per month average, I bring my food to work, I try to do as much as possible from scrap), I don't spend as much time/money in bars or other social activities as them, and I don't take trips across the globe (I am lucky enough to have enough family-owned places to spend my vacations at, I also avoid flying far for ecological reasons).
