A friend and I have bonded over appreciating the "shit" things, like white bread toast and hotel coffee and I think that's quite a good habit to instill. I love coffee and will hunt out the best spots in any city for a single-origin V60 on ice, but I am equally content in a diner when the only option is literally just "coffee".
Also studying art & practicing photography has made the world a much more beautiful place. Some of my best pictures have been taken in places that are usually considered unphotogenic.
To quote Reggie Watts:
Listen, invest two hundred dollars in a pair of good headphones Take care of ′em, put 'em in your ears, listen to the music Listen to how it′s supposed to be recorded You're missing, I swear to God, forty to fifty percent Of the music that's in there in the first place So if you wanna go back and listen to The shit that you thought you liked You might even like it more, motherf*er
This did inspire me to get better headphones and I have no regrets! I think some parts of the aversion to getting too fancy come from the reasonable ideas of: not wanting to lower your floor, avoiding the hedonic treadmill, and not wanting to increase your burn. This kind of does make sense for coffee: a lot of coffees you get will be out of your control and increasing the fanciness of your coffee is an ongoing expense. For headphones though they're all moot. I can't remember the last time I wore someone else's headphones, and it's just a pretty small once off payment (these have lasted me 5 years). I would strongly recommend upgrading in this department.
As for TVs, I rewatched Alien on my friend's new LG OLED and it was absolutely stunning. I am looking forward to getting a new place and having a nice set up like that. Again just a once off thing.
And just for balance, my computer monitor which I use all the time has an annoying flickering issue that I have just been putting up with for a long time.
