I think that a great leader can make a great organization and people.
So, It's difficult to become a great leader and have a leadership= 
You should have leadership skills  that can lead people 
to the right way.
When it comes to say stress of leadership,=stress , I think It's natural and a leader must take these kinda
stress as a their fate.=stress is a normal and expected part of our lives.

Sometimes people who runs=run some organization and company can be faced the fork of a road which will be a good choice or not.
I understand that very well.. It's extremly stressful.
