I know it
seems like all of those things are important to you, but they really aren't.
They're mostly just passing momentary fascinations, so either act on them or let them go. If something actually is important, you'll come across it again, or simply remember it.
I struggled for years with tons and tons of unread tabs, forgotten bookmarks, endless unstarted projects, hundreds of unwatched movies, unlistened albums. Learning to just let them go was the best thing that ever happened to me. The important stuff tends to stick around in memory, all by itself.
As a small part of that, I've instituted a "24 hour minimum" rule. If I see something I like, I add it to the shopping basket or save it in some other way that's not immediately visible when I'm on my PC or phone. Then I wait at least 24 hours. If I still desire that item after the waiting period has passed, I'll consider buying it. It has saved me so much money, and helped me avoid a ton of junk that would otherwise just be taking up space in my home.
Keeping too much stuff "active" is stressful as hell, and it's wonderful to be able to just not care about it.
