oh, i know exactly what you mean... when i was a child i could spend an entire day reading (in fact that is what i mostly did, when i was not in school), and now work, and housecleaning, and grocery shopping, etc. get in the way of so many more worthwhile activities (like reading)... it is very frustrating. i get cranky about it too, pretty regularly.
of course, it would help if i spent less time on this forum as well...
