This is such a hard question. o.o
Erm... One of the first responses to this question would be to exist in a world, and have the same journey that the main character did, though with hopefully much less death and sorrow along the way, as the book series His Dark Materials, (Golden Compass) existed in. A world daemons, a knife to cut through the very fabric of the universe, Spectors, and all the rest...
It's a good series x3
