“Let's try and pay more attention to what's around us. Look up. Look down - if only so you don't trip. Ask questions. You know how kids always ask "why?" Ask why. Then ask why again. And then ask why again. And then ask why again. And then ask why again. And then ask why again. And then ask why again. And then ask why again. Don't stop asking why until you get the answer you're looking for. Or until you're escorted away by security, whichever comes first.”
