That's always been in my mind my metaphor for a team working really hard on something they're passionate about. It's that through the team, through that group of incredibly talented people bumping up against each other, having arguments, having fights sometimes, making some noise, and working together they polish each other and they polish the ideas, and what comes out are these really beautiful stones.
