When wandering the world, forget your business cards. Don’t look for more contacts. Instead, observe. Say hello to the people you see every day, but don’t make a fetish out of it. Stay interested in others. Be generous in your attentions but not showy. Don’t wink, snap your fingers, high-five, or shout, though laugh with those who do. It bears repeating: Look around. Remember names. Remember where people were born.
