For example, a house with a pool may bring to mind the opportunity to hold pool parties. But most such plans will probably fall victim to akrasia, and even if they don't, how often can one person throw pool parties without exhausting their friends' interest? Pool parties may be fun to imagine, but they'll probably only affect a few hours every couple of months.

I told my family exactly this when they wanted to get an above-ground pool. Sure enough... eventually it just got damaged enough that we threw it out.
