Leadership is a very important yet misunderstood subject.
There are people who are the managers, HOD's, CEO's etc. But who the leader is, can be--as is often the case--different.
Leadership is also a multiplier effect. Having your workers "work harder" or longer hours doesn't make it more effective. Good leadership provides multiplier effects that makes 8 hours of work turn into 16 hours of effectiveness. I would rather have a great leader with people working 7 hour days than a lousy leader with people working 16 hour days.
Church is one of the best places to develop leaders. Why? Because there leaders become leaders purely from leadership capability, not like positional or rank status like in corporations or in the army.
Which leads to another thought, what is the "real world". Terms like "when I enter the real world" or "it's different in the real world".
We are born and study for about 1/3 of our lives. We then work for another 1/3 and live retired for another 1/3.
If the working world is the "real world". Then it seems we live in a "fantasy world" for 2/3 of our lives.
Your life is real whether you are a child or retired. The terms "real world" seem to imply that the 2/3 of our lives that we live in the "unreal world" seem to be unimportant and trivial. It then seems to be the cause of people neglecting the growth of their children when they are busy "pursuing their career" (whatever the word "career" means) and the purpose of their lives after retirement. (If there is such a thing as "retirement").
