There are three works of fiction that will change your perspective of this mundane existence forever.

The Foundation Series (Isaac Asimov):

Psychohistory - a fictional concept so brilliant, that it could almost be real. History is used to predict the future. And not predict as in crystal-ball-psychic prediction. More of an if-you-throw-an-object-at-velocity-v-and-angle-θ-in-vacuum-in-presence-of-gravity-where-would-it-land sort of prediction. Once you read this, you'll understand how the universe is really a huge complex system of random or deliberate triggers and directed events that follow the path of causality, and an infinite number of such paths being formed simultaneously.

The Matrix (Wachowski Brothers):

Everything is maya. All stimuli that you experience is the result of electrical impulses in the brain. And hence, if you give those electrical impulses directly to the brain, you can avoid the inconvenience of reality. And it would make no difference to a human whatsoever, as long as his/her body brain is well nourished and kept alive. Once you see this, the nature of reality will be understood.

The Selfish Gene (Richard Dawkins):

Evolution isn't a "process".  It is something that is inevitable. As inevitable as the fact that if you throw a ball upwards near the earth's surface, it will come down; as inevitable as the fact that if you try to try to herd a bunch of cats, you would fail. And it happens whether you believe it or not. And hey, if you study it, it actually follows really cool mathematical patterns. Once you read this, you'll look at the whole world differently, and understand things you've never understood before.
