Two Oughts of Life
To the best of your ability, and in relevant epistemic circumstances, align the degree of confidence you place on your beliefs with the evidential support for those beliefs insofar as that evidence is available to you. This project might involve an ongoing effort of doxastic adjustment as you discover new information and develop your capacity to understand the epistemic relation between evidence and belief. (Note here that I am suggesting that beliefs are degreed mental states. In other words, roughly, to believe that some proposition is the case is to take that proposition as true with some degree of confidence above .5. The specific degree might increase or decrease as one obtains new information relevant to the matter at hand.)
Similarly, align the strength of your valuing attitude toward something valuable with the objective worth of that thing. In other words, things which have objective value deserve to be recognized as such. (This is called the Fitting Attitude (FA) analysis of value.) So esteem them in a way that corresponds to their importance. Value the axiologically small things smally, the big things bigly, and the highest thing(s) with a fittingly highest mindset of evaluation. Don’t value that which is not valuable. Make pertinent modifications to your axiological attitudes — which like beliefs are degreed mental states — as your capacity for judgment matures.
