Great?

Why is Gatsby great? At first glance Gatsby seems to have it all. Then after you see that, you look deeper and you see he is flawed. Gatsby was great because he was able to take the life he wasn't satisfied with and create a new identity for himself when he felt like he needed to be someone else. Gatsby's desire to getwhat he wants, his desire to be "great" is so over powering and amazing. He had one goal: daisy, and that's exactly what he got. Well, at least for a little while. He is a closet romantic and people see him as great for that. I mean, hey, he built his life around one girl.
Gatsby is also a really terrible, not-great person too because the way's he goes about reaching his goals and getting the money he needs to live the lifestyle he wants to live are not typically respected ways to do things.  He illegally sells alcohol. I believe he is a pathological liar. He tends to lie about  everything. Maybe its that he just fails to mentions things. I guess that is lying by ommision but whatever. He is a liar. Liars are not good people. At all. Parents and every other sane adult on this whole planet would agree. Liars are not great. Therefore Gatsby is not great. What is great anyway? Does any body really know?
