To calculate your overall happiness, you take out a few counters from The Box. Lets say... A yellow counter for happiness, and a black counter for sadness. Now depending on what kind of mood you are in, affects the currency exchange rate, but lets say you're feeling quite neutral right now, so each black counter is minus one, and each happiness counter is plus one. After picking out several counters from the box, you realise you're on a minus number. All your worries and fears have been drawn out from The Box, and they stare back at you coldly. You'll want to add more yellow counters because happiness is a good thing right? So you try and reflect upon the good things - almost desperately to get to '0' or a plus number. Sometimes this is quite difficult, and sometimes you count the black counters as minus two or three, because you feel quite sad.
But no matter your calculation, you don't have to stand by it. When have numbers or math ever served you in a light-hearted conversation with your friends, or the feeling of warmth - either from the sun or just simply from a smile? Take a break from fighting the world, and make your own personal revolution. Break free from sitting in that dark room and counting... And make your own rules to happiness.
