Alas! the day cometh when man shall no longer shoot the arrow of his desire beyond man, when his bowstring shall have forgotten its use! I say unto you: a man must have chaos yet within him to be able to give birth to a dancing star. I say unto you: ye have chaos yet within you. Alas! the day cometh when man shall give birth to no more stars. Alas! the day cometh of that most contemptible man which can no longer contemn himself.

— Thus Spoke Zarathustra, Nietzsche

Me :  Competition around is not the only barrier one needs to overcome to “do anything” in “anything is possible”. There are a lot of non-human barriers for example, like gravity.

Carpe Diem : “Gravity”. Why would any (reasonable) person see the (immutable) constraints of the natural world as being identical with the (situational) constraints of the social world and treat them at the same semantic level?

I think Carpe Diem used a fortuitous choice of words in that rebuttal. I have hence found myself feverishly reading these words of a renegade psychologist.
