Okay, I'm dating myself, but when I was in grad school, there was a campus computer store, and they gave out a little pamphlet: "Do I need a personal computer?" It listed a number of pro's and con's, but the message that has stuck with me is this one:

Don't expect your computer to organize you. If you have a messy desk, you will have a messy computer.

Decades later, I have both a messy desktop and a messy computer. I think there is something about personal organization that, if it eludes you, it will elude your computer too. I've made peace with the fact that I will never be a hyper organized person. The best thing I can do is to put my stuff somewhere and hope that it's searchable.
