GAL doesn't have to be time consuming and can be small changes. Remember the "butterfly effect" MWD talked about? Think of some goals and plan a way to meet those goals.
Maybe you have a goal to be healthier and to meet that goal you plan to quit smoking, cut back on drinking, lose x amount of weight, drink x amount of water a day, cut back on fast food, etc.
Maybe you used to have a hobby like reading and haven't done so in a while. You could get audio books to listen to on your drive to work.
