Cast Iron Skillet, take care of it and you will pass it down to your children.

A Time Timer.

They're not cheap, especially for a timer that's bare bones (~20 USD).

But it has changed my work life.

1. People who want to interrupt me while I'm working can now see how long until I have my next break. So I am interrupted less.
2. Now I self-regulate a bit better, so I'm able to work longer without destroying myself in the process. I take breaks that help me with repetitive strain injuries and with feeling like I'm a human being and not just a machine.
3. Now I remember to actually start timers when I start working. I know this is a bit silly, but I was having trouble creating a habit of stopping for breaks. I tried to solve this by setting timers on my phone, but I constantly forgot doing it. Now I'm reminded to start a timer by something that I see on my desk.

Any basic ear plugs, literally $2 to make the world nicer, to sleep better in loud situations, to protect your hearing, to prevent infections in pools, and more.

You don't realize how much nicer the world is when it's like 15db quiter, especially when you are in a city.

Some chifi buds and a (Bluetooth) dac.

I have a pair of kz prx (planars, 37 bucks) and a hiby w3II (good enough over by and oké over cable, 40). If you don’t need by I will recommend the trn black pearl as it has the same parts as some of its more expensive counterparts

Multitool. Can't live without.

You really should buy a bedbug proof mattress cover and interceptors for the legs of your bed and furniture. Trust me when I say that an ounce of prevention will save you a lot of trouble, cost, and emotional trauma. Even if it costs more, buy then anyway.

Electric kettle.

Rechargeable head lamp.

Nice EDC knife.

A really good insulated cup.

For me, literally game changing item is a game controller. For the games with native controller support it is awesome. Its easier and more confortable than mouse and keyboard. Of course it is not comparable with mouse and keyboard, especially in games heavily relied on mouse, but for anything else, on my opinion, it is a better option. My controller is quite cheap, but works well. I bought a controller to see what it is and how different it is for gaming, compared to mouse and keyboard. At first it was difficult, as i did not have an experience with controller, but now i enjoy it.

I was gonna say an OLED monitor but then i saw the 100$ or less
