I view everything around me as a figment of my imagination. See, I invented the Internet, people! With imagination like this, I could become the new Stanley Kubrick/Baz Luhrmann/Tim Schafer!
On a more serious note, no matter how optimistic I am, I can only see the downfall of humanity coming sooner rather than later. The problem is, humans just can't run the world; so long as they are, corruption, hate, crime and just plain dickheads exist, and they unbalance the rickety bridge of the world.
I am an environmentalist; I've done my fair share of planting trees. But when I see my friends and other passers-by do stupid things like smoke, litter or vandalise, it brings a tear to my eye.
