Why Are Human So Greedy?

Yap. Human are greedy. Tell me why!

I think I'm part of human, so I can't denny if someone told me that I am greedy. I don't know why I always feel I'm really bad at writing or I am sucks at writing or my writing is not good at all when I read people's writing which on my opinion is quite good. Good enough to be read. This is ridiculous when you felt down just because you read a fiction which has good story and the author smart enough selecting the words even if the story length isn't too long. While you, with your own story that has SO MANY words, felt like shitty when you re-read it.

Maybe I just too....why should I named it? Perfectionist?
Maybe I just compared my writing with those writing....

Or.....maybe I'm just greedy?
