Happiness. What is happiness? Have you ever thought about this realties? Of course thought! All sooner or later think about it. For every "it" is different, this "happiness". For every "it" her.
In my opinion, everything is much simpler. What would be happy do not need much, it is enough optimism! Happiness is in the details. Little things that we have forgotten how to see. Remember when we were kids, we were fairly new toys. Of course, I'm exaggerating, but you get my point)
