I like your idea about putting the toothpaste that needs using up in plain sight.

The only decluttering I've been doing is my email inbox. I finally worked out that the thing that was holding me up was that lots of the emails that I was getting stuck on had URLs in them, so I made a 'look at it later' folder for 'links to follow up'. I'm now down to <300 emails in that inbox! Yes, there is still a lot of work to be done on sorting out which of the links are actually relevant, and which ones were dealt with at the time, but at least they are being progressed!
