@chbartist, Few aspects of human behavior have been subject to as much speculation and discrepancy as group behavior or society; in effect if we accept the natural characterization of man, we will understand why some people; feel the need to cover or do themselves so many things, not trusting others, remember the cliché "if you want something to go well, do it yourself". It is a criterion I would say secondary to praise its success.
It is a model of individual behavior, involved in the "traditional" approach only recognize it performed by you, is a type of harmful ego.
I quote what is written by you; "We can be good or really good at many things, but there is no way to be a teacher in everything we try. (The world is a team, there are others, there is a variety of facts).
A high or excessive self-assessment, as to your person is not a sufficient condition to get to do great, the creation of the supreme or superior force, indicates that the world the diverse in everything and everything is based on the link of that diversity , understanding that the genius of leadership, is in delegating and giving opportunity to other beings.
he genius of leadership, is not in the fact that you do everything, is in the fact that MOTIVES to others do everything for a whole.
The greater the search for understanding, the greater the reward in the satisfaction of knowing ourselves
