His quote "God is dead" is supposed to indicate the genesis of nihilism.

Without a higher purpose, we fall into a belief that our lives are worthless.

However, we can find our own "god", whether that be helping others, mastery of a skill, or finding contentment.

There are plenty of things to find value in, just because Nietzsche had a complete breakdown in the pursuit, doesn't mean he's wrong.

When I make the decision to stare at my phone while crossing the street, I may be a hypocrite, but it doesn't make "look both ways before crossing" bad advice.
