““The longest golf drive recorded was hit on the moon. Man has yet to return to the Challenger Deep. The lesson from this is that it is easier for human beings to push outwards than it is for them to explore inwards. The wind that carries you away like a kite will blow you on your back if you turn to face it. Consider how the surface area of a balloon grows when air is blown into it. When we push out, we create new frontiers we might populate. When we take the air out of a balloon, it deflates, and becomes shrivelled.””
