Can leadership be taught or learned?

I believe leadership can be taught and learned. Leadership is based in a certain set of skills and traits that can be taught and learned. Not every leader needs to learn how to be a leader, some people have that set of skills and traits naturally, those people are natural leaders but the ones that don’t have them naturally, need to learnt them. But will they be as good leaders as natural leaders? Probably not, of course there are exceptions and each situation is unique, but when behavioral traits are learned and not natural they don’t have as much impact and forcing those traits can be quite tiresome. Leadership can be taught or learned but I don’t think that learning it makes someone automatically a leader, the person would also need a lot of practice and experience and most importantly, motivation to be a leader.
