Adderall has helped, so has some behavioral approaches, but nothing is a cure. For me, trying to eliminate distractions is either a distraction itself or ineffective.
Structured procrastination is useful, at least I am practicing piano or getting more fit instead of sitting around watching TV or reading dumb articles and forums.
The biggest problem is that I am randomly bored and watch a youtube video. It's just 15 minutes after all, how much could it hurt? and then I waste 2 hours which is 105 minutes more than I had when I started watching that video. Maybe I should play mobile games because those have those pesky daily energy limits that stop you from playing more.
Helps I got a side gig playing music haha but my bookmarks on that are gargantuan. The dancehall reggae section alone is massive. I never listen to that and get stuff done, really the best concentration music for me doesn't matter the BPM it just has to be mostly free of lyrical content. So work music is mostly electronic or classical.
What are you listening to that's high BPM for work? That hard techno shit out of Europe lately is a lot of fun, Anetha is incredible [1]
Anyway, my pet theory is that the fast music acts as a stimulant, raising activity in every part of the brain - including executive function. Same principle as amphetamines.
Shit is WAY too spazzy for me to focus though, I guess you guys got different brainwaves than I do. It's funny because in the suggestions I got this, titled pov: you have adhd (breakcore mix) [1]
I think personally what I like about them is as much as they're not above taking some sample and running it into the ground, they have a really good ear for melody and pathos. IMO all their best songs start by them going "this anime soundtrack is great, but it could be about 25% faster and more high pitched and backed by a really hard beat." And you know, they're usually right.
A really good example for me is [2], Jersey*Spirit, which is a remix of Try Unite! [3], some anime opening. I think depending on which you listen to first you're going to have a totally different idea of how that melody is supposed to go, because as far as I can tell without a music education, by inserting a break with a slowed down voice sample and leaving out some parts, Sharpnel's version puts the verse emphasis on a totally different measure than the original (the "fly away" part is the "B" measure in the original, and the "A" measure in Jersey*Spirit). Would you have heard that was in there? I wouldn't! And I'm not making a statement on which take is better, but to me, having heard Sharpnel's take first, the just original seems unbearably slow, and also they should put that melodic idea in the center instead.
edit: And that's how I learnt that HNews strips unicode symbols...
edit: Also I challenge you to listen to Watashi wa Maid without getting it stuck permanently in your head. [4] but note that the album art is very nsfw. (Yes this was the only version I could find. Youtube probably keeps taking it down, can't imagine why.) Then compare to the [5] original - if you can, without falling asleep!
edit: Also that's from a hentai OVA. I should note that. Fucking Sharpnel, how do they find this stuff... but you can't argue they don't elevate it above the source material.
edit: As a final link, here's a (VR) DJ set they did recently that I like a lot. [6] It's less of their own songs and also a bit slower and less hyper. Might be more to your liking.
