I'm re-reading Red Mars, which tells the story of the colonization of the red planet. Kim Stanley Robinson is one of my favorite authors because he can put you in the shoes of a person standing on another world.
That's useful to me because I live in a part of the world with four seasons, and we're currently sliding into one of the four that affects my moods. The way I can fix that, though, is to realize how magical it is to be alive on a planet that is powered by a gigantic furnace 93 million miles away.
No matter how sad I get, no matter how disappointed I am, no matter how much negativity my species is capable of, I am always able to put that to the side when I can take a parallax view and set my mind to right.
I really recommend the book, too.
