I've found that while I can keep a lot in my head, my ability to prioritize doesn't maintain the life of the thoughts. Everything is some form of Todo list but they range from tasks I need to do to ordering my purchasing habits to fit within my financial constraints to listing books, movies and TV shows I want to watch. Working an 8 to 5 plus a side business with kids means my time is very limited. The less I need to remember the better and trying to go from work mode to relax mode needs to be as easy a transition as possible. Otherwise I just stay working.
