Worthlessness is the default condition. - Jordan Peterson

Thinking leads inexorably to the abyss. It did not work for Tolstoy. It might not even have worked for Nietzsche, who arguably thought more clearly about such things than anyone in history. But if it is not thinking that can be relied upon in the direst of situations, what is left? Thought, after all, is the highest of human achievements, is it not?
Perhaps not.
Something supersedes thinking, despite its truly awesome power. When existence reveals itself as existentially intolerable, thinking collapses in on itself. In such situations — in the depths — it’s noticing, not thinking, that does the trick.

Your values have to be hierarchically organized with something absolute at the top, because otherwise they do nothing but war. This is true if you're an individual and it's true if you're a state. If you don't know what the next thing you should do is, then there are 50 things you should do. Then, how are you doing to do any of them? You can't. You have to prioritize. Something has to be above something else. It has to be arranged in a hierarchy for it not to be chaotic, so there is some principle at the top of the hierarchy.

It's a luxury to pursue what makes you happy; it's a moral obligation to pursue what you find meaningful.
