What is Greatness? (Was Lennon Wrong?)

This is John Lennon: 

       He once said that he was the Walrus. The later corrected himself and said Paul McCartney was the Walrus. It now appears that he is wrong once more. In reality, Friedrich Nietzsche was the Walrus:

       A question which comes up in all our busy brains at one point is the following: what is greatness? This same question tickled by brain as if I had consumed a Pan Galactic Gargle Blaster. So tell me, what is greatness? I've heard that Lennon was great (he was also wrong). I've heard Jesus was great. I've seen mugs labeled: World's Greatest Mom. So I wonder, what is greatness? Nietzsche, being the mathematical type, developed a formula. Thank you Nietzsche! His formula for greatness in a human being is Amor Fati.

A potent drink invented by Zaphod Beeblebrox. The effects have been likened to having your brains smashed out with a slice of lemon wrapped round a large gold brick.

There are many voluntary organizations which will help to rehabilitate you after you've had one.

What Does Socrates Teach Us?

This ugly man below is Socrates: 

Yet don't let his appearance distract you. Socrates teaches us to be intelligent non-conformists. What is an intelligent non-conformist? This terms refers to a person who does not submit him/herself to the rules of society. We should avoid acting like mindless sheep in a herd and instead act upon what we feel is just and appropriate. We should not acquiesce to the norms established by our peers if they contradict what we believe to be correct. 

Socrates also provides us with a method to practice philosophy. This is the Socratic Method: (1) present thesis, (2) provide a counterexample, (3) refine thesis and repeat until no counterexample can be utilized. 

Through the Socratic Method, one attain a clearer understanding of the argued topic in the pursuit of establishing a concrete conclusion or answer. Moreover, this method allows us to question the social conventions of society, avoiding the "herd" mentality.
