I try to keep a fairly small number of sub folders that are well named. I keep a file that lists what each folder is for. I also like to keep a TODO.txt that I append to the top with a date an what needs to be done next. I write a few tests and some good comments on code that I feel is likely to change. There is always the tendency to not write either of these, but I think it is important if you want to iterate fast.
