Cheers for sharing the great insight, and certainly there's more than meets the eyes when it comes to the art of leadership. It's not just a simple set of requirements or conditions to tell who can, or can't be a leader and it gets far more complex than that. It's also not just the mettle that one earns through experience, but their ability to stay cool and level-headed when times get tough, and people are looking for a way out.
Some leaders are borne on their first trial and tribulation, some others take time to mould. It's different depending on the person, and I do agree that leadership is beyond a set of skills, as it takes a great strength of character too. No leader is perfect, and being able to have that trust and understanding helps to balance their decision-making, and the effect that has. It's worth it for leaders to learn and listen from the people around them when it comes to subjects that are beyond their understanding, even if they have the ability to lead people through it.
