It’s easy and hard at the same time.

Eady because you derive that directly from your hierarchy of values.

Hard because you can’t just “decide” what your hierarchy of values is. There is a significant transcendental part to it that critically depends on other people, on your environment, even God.

This is why many stuck in a limbo of analyzing and rationality justifying their goals.

So eventually all people do the same thing - they just pick whatever their intuition tells them from available options. That’s the framework.
