I have a friend whose mantra is: “stay in your box.” By that he means to focus on your own area and don’t get sidetracked into other areas which aren’t your responsibility. From one perspective, this is solid advice. The more you focus on your own work, the more likely you are to be able to complete your tasks with excellence. From another perspective, it can be a career killer. If you become the very best in your “box” but never take an interest in other areas, assisting or contributing for improvement, you may find that it becomes nearly impossible to break out of that “box.”
