YOU CAN NEVER GO BACK. FREE MARS.

"Have we ever been so free of choices? The past is wiped out, all that matters is now. The present and the future. And the future is this field of stones, and here we are. And, you know, you never really summon all of your strength until you know that there's no way back, no way to go but onward." ~ Michel, Red Mars, Kim Stanley Robinson

"You have to fight not only against what you hate, but for what you love, you see? And so you have to find out what it is you love. You have to remember it, or create it." ~ Michel, Green Mars, Kim Stanley Robinson

"We'll win in the end. Mars right now is the battleground of past and future, and the past has its power, but the future is where we're all going." ~ Nirgal, Blue Mars, Kim Stanley Robinson
