According to the Myers Briggs personality testing, I'm an ESTJ (or ISTJ depending on the day). I love keeping our living space organized and I'm good at doing that. Organizing makes me happy because it's something I'm really good at doing and it energizes me. Win-Win.
Organizing is not the be all, end all to life, but it is a tool that has enabled us to comfortably live, work and learn at home, many of those homes being relatively by North American standards.
