Chair. Never understood why somebody would pay for a chair more than 50-60 bucks. Something you can get in staples/wallmart anywhere...
My friend bought Herman Miller for ~$1000 and I called him a donkey.
Then started a job where we had these chairs in the office. Noticed it. Even back when I was broke, rented a room and didn't want to buy anything that would be potentially a problem to move, I still decided to buy it. I use it 6-8 hours a day. Worth it.
2) Higher quality kitchenware. knifes and frying pans. I actually had to go over few iterations cause even though I got more expensive ones they still didn't work well. Now, though, it significantly improved the quality/cooking of my food
3) High quality headphones/ear buds. Something about great quality sound makes it so much better to work out. I can run longer with proper soundtrack.
4) Car that I really wanted. I get behind the wheel and literally enjoy holding it my hand. comfortable/fast/smooth. looks sexy. It is an esthetic pleasure.
5) Very good laptop and widescreen curved screen. using them for work everyday - makes total sense to go with top of the line.
I think it would very cool to have washer/dryer in unit. I don't have that. carrying a bag of underwear to another building in 2020 seems unnecessary.
P.S coffee maker. ~$700... I feel like it payed for itself in first month. I love coffee - it makes it itself. no standing around holding a cup of milk.
