George Santayana

It is only when you watch the dense mass of thousands of ants, crowded together around the Hill, blackening the ground, that you begin to see the whole beast, and now you observe it thinking, planning, calculating. It is an intelligence, a kind of live computer, with crawling bits for its wits.

I have to feel that I'm going somewhere all the time. By definition, if you have this urge to go places, then you can't be 100 percent happy where you are. It's not like I enjoy being miserable for weeks on end. But I think it's good to be miserable for about one day every third week - that's ideal for me.
