I settled on Memmy early on as the least buggy app, but I like Voyager quite a bit as well. I might switch if they let me change the color of upvote/downvote arrows to what my brain expects.
I took up biking about 3 years ago, and I definitely have a lot less nervous energy after a ride and can focus on mental tasks better. The post-workout endorphin high may be part of it.
BTW - not personally experienced with ADHD; just came across this in All.
City of the Sun is some fantastic Latin-inspired instrumental post-rock. (That’s probably drivel, idk what genre they are).
Their cover of Young Folks is how I found them, but their self-titled album from 2020 is probably one of my favorites of the last several years. It’s a good balance of calming serenades and powerful melodies.
Hon. mention - The Samuel Jackson Five - Easily Misunderstood is another old favorite of mine. Angrier and edgier, but still haunting in its own way.
The Beastie Boys also have a couple fantastic instrumental jam albums - The In Sound From Way Out, and The Mix-Up.
In 2016, the school's co-founder and director, Susan Gayle Clark, was convicted of child neglect and failing to report and was sentenced to six months in jail.
After looking at the upgrade options (and shopping with your wallet, not mine), I'd say buy a MK4 kit. You're in a fairly unique position that you aren't taking apart a working printer; you're getting a new printer with 2023 electronics and motors for a discount.
However, if sinking that kind of cash isn't wise for you right now, then build what you have! Or, pick up the MK3S+ upgrade kit for $50USD. MK3S+ is a reliable workhorse, and mine won't be retired anytime soon. It still prints PETG as well or better than my X1C, if a little slower.
