During the evolution era, a strong leader is required. There will be no one around the strong leader who can against the strong leader, because it is very difficult to against to such a strong leader.
The leader can proceed with the evolution efficiently if the leader's idea is correct but if not there will be chaos.
The leader should always collect different ideas and opinions and verify whether the leader's idea is correct or not. The leader should always check that he is not a naked king by honestly seeing mirror.
