A "gaming mousepad", which is basically a padded surface that goes over the entire space of your desk where your hands may be. So my hands can be anywhere I want them to be, and still be comfortable. It's always worth paying for ergonomics in my mind, I buy high quality mice and keyboards (the Logitech MX Vertical and the Keyboard.io Atreus/Model 10, though I didn't but them this year), I add aftermarket padding to the arms of my chair, et cetera. You don't have to get stuff that's as expensive as what I listed, I have a pretty severe RSI and need top-of-the-line gear just to function as a programmer typing all day, but don't skimp out on this stuff & end up with an RSI. If you have discomfort, deal with it early. If discomfort becomes pain, stop what you're doing and take a walk. (/PSA)<p>Various desk decorations, such as an analog clock and a small whiteboard. Making my desk a pretty space makes it easier for me to respect it, and reduces the problem of crap accumulating on it just because it's a flat surface at arm height. When there's pretty stuff, crap makes it look ugly, and this bothers me so I deal with it. Otherwise, it just looks like a place where crap goes, and the crap doesn't bother me. The decorations also break up the flat surface and make it so there's less big, tempting flat space.<p>An analog kitchen timer. This allows me to time box things without looking at my phone, a recipe for distraction. It also has a rhythm which gently reminds me the timer is running without making me feel too rushed.<p>A power strip with USB outlets. It's a nice convenience at my desk, but it really shines when I pack my stuff up to work somewhere else, like when visiting family. If I can get access to 1 outlet, I'm good to go, and I don't need to use a bunch of charging bricks to charge multiple devices. I don't have to worry about having to unplug a lamp and then remember to plug it back in when I'm done, or anything like that.
