Jordan B. Peterson speaking in the Introduction to the Idea of God:
Have a noble aim. Otherwise you have nothing but shallow, trivial pleasures. And they won't sustain you. And that's not good. Because life is so difficult, so much suffering, so complex. It ends. And everyone dies. And it's painful. Without a noble aim how can you withstand any of that?
The noble aim, what is it? It's encapsulated - in part - in the story of Marduk. It's to pay attention, it's to speak properly, it's to confront chaos, it's to make a better world.
... and that's enough of a noble aim so that you can stand up without cringing at the very thought of your own existence, so that you can do something worthwhile to justify your retched position on the planet.
Harsh but fair.
