If you cleaned really frequently in small bursts (say, for 20 minutes a day, almost every day?), starting from your "satisfactory" point, would that be enough to maintain the satisfactory point more or less continuously? Then each 20-minute burst of work would come with the "satisfactory state" reward.
Yes, this is what I try to do, and it is what I am able to do for, typically, a couple months at a time. Having someone else remind me that this is better than three hours all at once is good though. For some reason, I find myself slowly ignoring this advice from myself if I don't hear it from somewhere else every now and then. (avoiding this problem might be another good "stupid question"...)
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
To any future monthly posters of SQ threads, please remember to add the "stupid_questions" tag.
