I clean. I reorganize my house (still settling in yet), I find all the little odds and ends I've let slips over the week in this elusive thing called 'free time'. No time is -ever- free in my experience. It ALWAYS comes at the expense of something else I could be doing.
Like taking that walk around the block just to see how long it takes and to see what is down the road the next street over.
Or doing something in the yard.
Or fiddling online, of course.
I find I get the most done when I am waiting. For someone, for a specific time to come, etc. Means I finally have 'spare time' to do it.
I've termed boredom that time when someone chooses to not use the desire for "ANYTHING EXCITING, ANYTHING AT ALL' to do something I term 'creative' instead, which is merely an action someone doesn't want to do or that it doesn't occur to them to do and is fully within their reach if they CHOOSE to do it or to think of something new to their habits.
I've actually found that most of my friends with ADD have this weird case of it striking them constantly. And oh, how they hate it.
