This cartoon from South park is actually so great!
I mean to be able to appreciate the good stuff, we need to have felt the bad.
In order to feel sad, you must have had a memory or a moment in that made you feel that happy, that invincible.
Each day that I wake up and I can tell its not a good day, I know deep down inside under neath the crazy, I’m secretly so happy that I have such a chance to really appreciate the days when I am happy and can achieve things.
It is strange it has taken be four years of bad days to realize how lucky I am that I can feel happy and sad.
