How do you define a leader? is he who drives team towards common goal? is he who takes all burden himself? is he the most skilled person in the group?
for me leader is the one who has got attitude to learn anything from everything he looks for opportunities in adversities and one who faces the storms himself before leading others in to it.
I think most of the great leaders had that inborn spark in them just that it had to be discovered. So if leadership is inborn what about others?
Leadership qualities can be developed but never learnt, and developing takes years of handwork and perseverance.
