I think I have created my new motto:
"Conserve your passion."
As a perpetually moving man, I often burn out on projects. I have a supernova of interest and shortly thereafter, I collapse into a white dwarf burning myself up. One of the tips I picked up from Robert Kiyosaki's books was to be an underachiever. Or, said in a more positive light, don't do everything you want to do right now, save some of it for later. I have found this to immensely improve my drive and interest in my various schemes. It also forces me to focus on those things for longer periods of... Look! Something Shiny!
