Filmmaker Alanis Obomsawin on the value of nature:

"When the last tree is cut, the last fish is caught, and the last river is polluted; when to breathe the air is sickening, you will realize, too late, that wealth is not in bank accounts and that you can’t eat money."

Writer David Foster Wallace on the importance of controlling your attention:

"Twenty years after my own graduation, I have come gradually to understand that the liberal arts cliché about "teaching you how to think" is actually shorthand for a much deeper, more serious idea: Learning how to think really means learning how to exercise some control over how and what you think. It means being conscious and aware enough to choose what you pay attention to and to choose how you construct meaning from experience. Because if you cannot exercise this kind of choice in adult life, you will be totally hosed."
