Ego and vanity (in my point of view) are the two biggest evils in our society today.
Social networks have boosted both too much.
Today, everyone thinks they are "important", "famous".
You can see how much human beings are currently limited.
They look at everything from the perspective of the Earth, from below, and forget that they are inferior to a Creator God, a sky and an immense universe above and around us, and that in the end they are nothing but "an atom" amidst all this immensity.
