here39。s another very important group: your family and friends. The people who, more than anyone else, loved, supported, and even sacrificed greatly to help you reach this moment. Let39。s give them a round of applause. This will be my first piece of advice. You might not appreciate until much later in your life how much this moment means to them. Or how that bond of obligation, love, and duty between you matters more than anything else. In fact, that39。s what I really want to talk to you about today. In a world where we obsessively document our own lives, most of us don39。t pay nearly enough attention to what we owe one another. Now this isn39。t just about calling your parents more, although I39。m sure they39。d be grateful if you did that. It39。s about recognizing that human civilization began when we realized that we could do more together. That the threats and danger outside the flickering firelight got smaller when we got bigger. And that we could create more — more prosperity, more beauty, more wisdom, and a better life — when we acknowledge certain shared truths and acted collectively.
