What is the difference between a natural leader and a trained leader and who would you want on your team?

“A Leader is what I believe is a person with enthusiasm, with initiatives, an attitude to handle situation, with an inborn quality of never letting him down. A person can be trained to handle & to shoulder responsibilities, but lack of enthusiasm, with lack of die-hard nature would be a set back for a trained leader. However a trained one can compensate to a level of contributing in the absence of an inborn. But pressured situations can definitely shape a trained person in terms of competency.”
