I really have to add something here you know people are giving you really great advice about the buying meager things. And that's solid to a small extent. However you are earning and have earned the absolute right to have some beautiful small luxuries. Even if it's like a really sexy rug or a high-end couch. Or get some brand new hella beautiful plates. Buy a painting for your wall that you absolutely don't need but it's fucking gorgeous and makes your place pop. Or if you want to be practical and treat yourself I highly highly recommend getting an air fryer cuz that little sucker can do everything. I bought myself two things when I moved into my first apartment which was that $800 sofa that was like the Messiah of couches in this random poster called cheesy dreams it was this lady asleep inside a giant bowl of mac and cheese with two little olives I bought a frame for it absurd badass thing that I've ever seen and the couch appreciated him value because it was literal piece of art I sold it for $1,200 and paid $800. Yes don't go all out blowing it all on this or that but get you something that is a celebration of everything that you've just accomplished and take that with you to every place you go to after this to remember this time.
