I saw Alan Mulalley give a speech to some engineering students while he still worked at Boeing, the biggest employer in the Seattle area at the time. He told them that 10% of the people design the aircraft and 10% of the people build them. So what do the other 80% of the employees do? They communicate between Engineering and Manufacturing. When you watch an exciting movie or TV series, do you hang around to watch the credits? How many people made it possible for you to live every aspect of your current life (with its running water, smart phones, and parking spaces)? What are you doing to make life better for others?
