I think the long explanations are what get me when it comes to Ospensky, Sarte, Kant, and others I've read. But Nietzsche I get because either his thoughts conciede with mine and his ideas are simple and straight forward. Or both. Plus he presents many of his writing in separate numbered thoughts that are random. So you can stop and think on one before moving on to another. So it makes for easy, so to speak, reading. You could read one thought a day or read for hours.
Like here's one that just came to mind ...
"The Christian resolve to find the world ugly and bad has made the world ugly and bad."
Reading his writings he was not a surporter of Christianity. But most of his points were supported by actions and events taken within the religion. This is one of those stand alone thoughts where you can think on what he was saying and how you take it yourself.
"That's the problem with drinking ... If something bad happens you drink in attempt to forget; if something good happens you drink in order to celebrate; and if nothing happens you drink to make something happen." -- Charles Bukowski
