Yeah Nietzsche is a tough old boy to read. I recommend reading SparkNotes along with Thus Spake Zarathustra, it will help, even if just a little. I've only read Zarathustra, so I'm probably not the greatest expert on him, but I did find that particular book interesesting. Maybe not entirely inspiring, but interesting. I read that when I was mentally exiting the JW cult, so I was impressed with how much you can expand your mind with such philosophies, once you pull your head out of the Watchtower's collective arse.
Dude had a helluva 'stache.
