Being gifted with ADD, I naturally tend toward extreme disorganization, but if I don't have some kind of system I end up not having everything I need. As a compromise, I've got a complete set of the usual take-along gear (tubes, tools, pump, etc.) that stays in each of my various bags and a moveable compartment that keeps the variable day needs (clothes and lunch) and move that to whatever bag I'm taking on a given day. So I guess I have a light organizational system within a overall dump-and-go system.
