I wouldn't say that I was a very chaotic person but after moving several times it felt like it takes longer to find some special tool than buy it new. So I created a little program to keep track of all my stuff [1]. It took quite a while to put everything in there but it helps me to check for a tool if a friend asks for something. Also, I like to be aware of what I own and what I should give away because I don't need it anymore.
