Irritants, disagreements, different perspectives, optional calls… how you handle these types of items shows a big difference between young leaders and more mature leaders. When I was young in leadership  I couldn’t let the little things go. Some of this was due to my personality, some of it was due to my maturity, or lack there of. In leadership you need to focus on the big wins, the mission, the overall objectives. You will know you are growing when you find yourself wasting less time and energy battling on minor issues, subtle nuances of how something can be executed and small interpersonal disagreements. Keep your sights and your leadership focused on the major goals.
