I think it is much quicker to go through the Ego and It's own by Max Stirner which I believe pre existed Nietzsche because I believe Stirner was born much earlier than Nietzsche
No one has convinced me that Nietzcshe has some great teaching that Stirner does not
I only have so much time to read books
If you have so much massive time as to go through Nietzsche
Stirner should be a quick read or listen to you
