Oh yes, I forgot to add one thing.
I'm sure you're familiar with the saying "Ignorance is bliss."
Also, there's another saying "Intelligent people want to learn, but fools are satisfied with ignorance."
So by cross-referencing, we can tell that fools are satisfied with bliss.
And intelligent people want more.
So from this, we can conclude that intelligent people are greedy people.
Also, being satisfied with bliss seems like a pretty wise thing to do, since there's another saying "Count your blessings."
So from this, we can conclude that fools are wise people, and since wise people are intelligent people, everyone is greedy.
So what have we learned from this?
To not be a greedy person, be selectively ignorant.
By doing so, you will be selectively blissful, selectively wise, selectively intelligent and selectively greedy.
