Burnout and the leader
Two of the major causes of burnout for people in leadership are (1) when the leader takes on more than they should or (2) fails to hand over aspects of what they do to others.
This second aspect of burnout is not just detrimental to the growth of the future leader but to the leader themselves, and to the organization they lead.
Great things may have been expected of the leader in the past but when they have done all that they can it is time to hand it over to someone else, who if resourced correctly will grow and be bigger and/or better than the original leader.
This handing over does not diminish the first leader but rather is a way of moving from success to significance.
It is important for the new leaders to be free enough to be able to make mistakes on the way, without the thought or worry of having the authority taken away from them. Micro managing of subordinates will stifle any creativity they may have. It is this creativity that will cause organic change and growth within the organisation.
