What does self-overcoming mean to Nietzsche?

Question

in detail, what does this mean, examples, and where does it feature in his works or other peoples work?

Answer 1

He meant that a person should go beyond selfish needs to look to what man in general can be. As long as we think only of ourselves, we cannot see what "mankind" (or "humankind") is capable of. An example is religion. He wanted men to look at it to see what was real in it, and he hoped people would ask themselves if they were just depending on a God because to do so was the conventional normal way to live. He said "God is dead" to wake people up to the fact that the God they believed in was dead, and that they needed to search for the real God, beyond themselves

Answer 2

From N.'s Thus Spoke Zarathustra:
"A table of virtues hangs over every people. Behold, it is the table of its overcomings; behold, it is the voice of its will to power. Praiseworthy is whatever seems difficult to a people; whatever seems indispensable and difficult is called good; and... the rarest, the most difficult- that they call holy."
Nietzsche's 'will to power' is synonymous with self-overcoming (the major theme of his work and his life -he viewed his writings as achievements of self-overcoming due to being plagued constantly with illness-) which is itself a continuation of Schopenhaeur's metaphysical Will as the driving force behind/through existence.

Answer 3

Friedrich Nietzsche was a man who battled his own demons for his life. Unfortunately he lost his marbles and his work has been twisted by his fascist sister and the 3rd Reich.

I can only give you this explanation:
Overcoming means that you have to be consent about your weak points and make up for them with your strong points.
In general you have to confront yourself with your own personality, god or bad.
And that's not an easy thing to do, that's why everyone tries to avoid it!
