Are you digital or paper?
I've got a program on my laptop I am forcing myself to switch to, which should keep work organized, but I also have a planner (with actual paper) that I use as well, for addresses and calender stuff, as well as notes and misc stuff.
I'll be trading in my cell phone for a blackberry within the next few months, which will sync with the software on my laptop, to try and go completely digital, but I'm terrified of loosing stuff.
What works for you? What hasn't worked for you? I used to use a spreadsheet to keep track of sessions and progress, but that's been taken over by the software. Certainly not as easy, but it should (once I get it all figured out) be more detailed.
