There are no wishy-washy astronauts. You don't get up there by being uncaring and blase. And whatever gave you the sense of tenacity and purpose to get that far in life is absolutely reaffirmed and deepened by the experience itself.

Because God is never cruel, there is a reason for all things. We must know the pain of loss; because if we never knew it, we would have no compassion for others, and we would become monsters of self-regard, creatures of unalloyed self-interest. The terrible pain of loss teaches humility to our prideful kind, has the power to soften uncaring hearts, to make a better person of a good one.

Love is bullshit. Emotion is bullshit. I am a rock. A jerk. I'm an uncaring asshole and proud of it.
