I would have made this into a longer post, but it works much better appended to this one:

It's clear that you can't just make willpower appear with a snap of your fingers, so I consider fuzzies to be utilons for many human utility functions. However, utilitarians have it even better -- if they get fuzzies by giving fuzzies to someone else, they get to count all of the fuzzies generated as utilons. I urge people focused on being effective utilitarians to keep this in mind if they feel like they're running low on fuzzies.
