If you have hundreds or thousands of tabs open... it may be a hint you have ADHD.
The tabs form a mix of a todo list (they're things you want to do but, because of executive dysfunction, you can't get yourself to do them), and a coping mechanism for "out of sight, out of mind" (which is common for ADHD). Bookmarks don't work as an alternative because those are out of sight.
If you're not familiar with it, executive function is the part of your brain that turns the knowledge that you need to do something into actually doing the thing. If that's not working properly then you'll struggle to get yourself to work on things (even things you want to do or that you know are important), and you'll also struggle to stop doing things once you get stuck into them (like, reading books for hours straight). It's a big part of ADHD (which, frankly, is very badly named, it's more dysregulation of attention than a lack of it, and you'd think hyperfocus being a thing would have been a hint to the namers but apparently not).
I'm pointing this out in the hopes that it helps somebody. ADHD is treatable, but first you have to figure out you have it, and most people only know wrong stereotypes about it rather than anything accurate that would let them recognize it in themselves. I really wish someone had pointed out some of the obvious ADHD things I do so I could've got it treated sooner... so here's my attempt at doing that for somebody else.
I suspect saying this won't go down well with the crowd here at /., the place seems to be infested with the sorts of people who would argue you're just being lazy or some stupid shit, but... that's not the case. It's an actual physical problem with your brain that can be treated.
