the worst thing is shower - away from mobile, need to keep repeating keywords of all thoughts like mantra to quickly write them down upon leaving shower
I have a similar problem. Often when reading my twitter timeline I will think to do some action based on a tweet, then keep scrolling and forget what it was. I would have to scroll back a few tweets to remember what that thought was.
as your help with going back, that sadly for me works very rarely anymore, is bigger odds that the thought will suddenly appear later when not thinking about it anymore, though i don't risk any of this and now just immediately follow new thought without postponing, I guess you could say I developed ADD thanks to progress in mobiles technology and internet, if it's possible to develop it, i used to be avid reader of books, but nowadays have problem to focus even on longer article, having child ruined even my movie watching experience, when because if limited time i FFWD scenes without talking and other filler to shorten runtime of movie, this coming from guy who was considering destroying Christmas decoration on public street because it was in my vision field when watching movie going through blinds
