Leaders can be made?
Erm, well, no. There is a big difference between a leader, and one who is in charge. We've had presidents who were in charge, but who weren't leaders. The mistake being made here is that while a leader can learn the detailed areas of their leadership to become better, someone who is not a leader can learn all that and never become a leader. A leader inspires, and sadly, that can't be taught. You can be taught to not be terrible, as in the things you shouldn't do, or say. But true leadership isn't capable of being taught, just honed. It's one of those things where "you either got it, or you don't got it".
