The hallmark of rationality is to focus on the process, not the product. Rationality isn’t logic. It isn’t not feeling. As above, emotions are an input into the prediction machinery of your brain. ‘Being rational means knowing when, where, and to what extent to be logical’[vi]. In terms of turning your resources into your Good Life, this is a process of defining your identity in relation to and in interaction with, your environment. You’re doing this all the time, mostly unconsciously. Because money decisions have such a powerful effect on this co-identification process, we need to pay great attention to this process: we need to turn our brains up, not off, lest we be sucked into an abyss of self-deception and self-destruction.
