nice post. However it might be better to characterize the first two classes as beliefs which are true because of the belief, instead of as false beliefs (Which is important so as not to unconsciously weaken our attachment to truth). For example in your case of believing that water will help you feel better, the reason you believe it is because it is actually true by virtue of the belief, similarly when the want to be rock star enjoys making music for its own sake the belief that making music is fun is now true.
