Now that I'm reconsiderng (and wondering why I am not the person in that video), I think that if I manage stress by having a little bit of time to myself everyday. It's difficult, because I'm the one that drops the kids off to daycare and everyone is home by the time I get there, but my husband is good at letting me go and take a few minutes after getting home before being bombarded by everybody. He works full time too, but he usually gives himself about an hour or so at home before he picks the kids up from daycare.
Lately I've been using that time to watch TV while folding clothes (or doing some other housekeeping) -- both things are a bit mindless, but doing one takes away the stress and guilt of doing the other.

I finished watching my recordings from last winter the week before the fall season started and am currently in the middle of my summer shows.
Reading and my other hobbies (video games, tv, scrapbooking, knitting) are nighttime things that I try to do just before getting ready for bed. I do notice that if I don't fit at least a half hour of
something at night, I later end up cranky and unreasonable.
