Thinking Makes Everything, 2008
"There are happy and sad moments, but thinking makes them so."
From Shakespeare's quote, I made my own definition for happiness and sadness. I wrote some neutral, everyday happening and put them randomly into two categories: those that reads in the right direction are happy moments, and the opposite, sad moments.
But seen from the other side, everything changes. So every emotions we face are eventually, man made. At the same time, both sides are required to complete the message, saying that both emotions are essential for all of us.
