I could never use the word 'perfect' for this type of thing, or for anything, really.
I prefer trying to think more along the lines of a system that is functioning well, or extremely well. But at the same time, its ok if it functions poorly sometimes as well, as long as its functioning at all.
So without thinking I tried to put them on the table a few feet away, as they were so big and heavy.
When I have stuff that doesn't fit into my inbox, I'll usually just write "deal with the envelope from ABC that's on the side table" on a sheet of paper and stick that in the inbox. Keeps the item in my queue to be processed without demolishing the stuff that's under it in the inbox.
