>Out of sight out of mind applies universally (sometimes good, sometimes bad) - I have the most success when I engineer my environments to put the things I need to focus on in front of me.
100% this aye. I had my bookshelf in my bedroom and I found sometimes I'd be late for work or to pick up the shopping etc as when I would sit down on the end of my bed to get changed I would pull a book off the bookshelf and start reading something that would help me answer a question that was on my mind. I took it and moved it down to the basement to sort that problem out. I've since moved a small selection of things I'm not hyperfocused on right now and hence can't really read, but know I should make my way through them and I keep the one that I'm trying to get through now on the bedside table. I've been making my way through it on and off, and it's going slowly but surely!
