One thing that I need to get better about is the whole idea in Getting Things Done about the read and review pile, specifically the part about "if it falls over, throw it out".
I don't tend to have a physical read and review pile, so figuring out when the "if it falls over" piece is a bit trickier. I have some scripts that I use for determining the age of something (which I usually limit to 14 days) but I've also tricked that by using `touch` on those files in the past.
