So, this has to be a hobby that requires
- little-to-no monetary expenditure, unless I can justify it as being for the household, like furniture reupholstery, or HGTV-watching, or extreme couponing (I do enjoy cutting paper with scissors...);
- little-to-no regular sleep--no operating heavy machinery...except cars carrying small children, large appliances operating near small children, and doors blocked by small children mid-tantrum;
- little-to-no space--I have no craft room, no desk, no attic, no basement, no crawl space, no closet space, no shelf space, and very little mental space. (The hobby is kinda supposed to fix that last one.)
I've already considered and discarded many excellent ideas--writing, reading, needlework, photography, coloring, singing in the shower, getting dressed, cleaning my kitchen, folding my laundry (into origami), and Zen Buddhist meditation. Plenty of options that cover bettering my environment, clearing out my brain, avoiding my brain at all costs, being more active, being less active, or being completely inactive. I could just pick one of these and go with it...but then what do I do when I get bored with it next week?
New hobby idea: Watch Cars every day. It fits all my numbered criteria, requires no special preparation--and I can do it regardless of state of dress, health, or mental awareness. I'll learn more via observation about the intricacies of digital animation, feature-length film plotting, and literary character development. I'll memorize all the words to Sheryl Crow's "Get Gone" and James Taylor's "Our Town." I'll be able to list each of Luigi's tire offers to McQueen--so far, the one thing I know is that they actually get progressively worse each time (I can feel you getting more impressed with me already).
This may take some convincing of Stephen--currently he only wants to watch it about 5 times a week. I'll just have to employ my sparkling powers of preschooler persuasion (they're vampire powers). It's important not to let your personal interests be neglected, even--especially--if that means your children don't get what they want all the time, so they aren't spoiled and you aren't burned out. Priorities.
