At the end of the day, just like at the end of this train, there is only one driver. Onboard the train, there are hundreds of passengers together with dozens of conductors. There might be many more passengers waiting at the following stations. There are thousands of support professionals, engineers, and management running different aspects of the operations. However, as you can see in the picture, only one person can sit in the driver seat.
At work and in your personal life, are you a driver, passenger, or support team? It might be that you are changing your rolls and seats, depending on the situation. Are you aware of that and act accordingly?
