Yes, I actually went through it all yesterday and there are some OLD items in there! That was its original purpose, a genuine backlog list for things that I wanted to get to eventually after I was current on things (Yeah, right... Hmm, I think I see the fallacy in that logic!). Not really a someday maybe list, but close.
So I am torn between creating another category for shorter term holds, or just plowing through those old items since if they were important enough to save then I should either do them or trash them. I did trash a few, filed even more, so I made great progress. They are in Outlook and are usually sorted by date, so for now I will just leave them and keep them in my review process for now. A lot of them are good 5 minute knock-out items.
A note - the review process can feel like a waste of time, but I think overall it is a good thing to devote some time to not forgetting about things. The problem is old open loops can be QUITE depressing, and closure is also good. The key is not to create any new undone things to fester as they age. Cleaning up after yourself is fine, it's actually cleaning up after others that creates most of my backlog. Not saying I am perfect, in fact I leave a lot of messes behind!
