manager(s) not leader(s).
In order to have distinctive and someone who can make the difference, what you need is a leader who is also a man of God. e.g. if there is no leadership like Moses, today Isrealis might still be slaves at Eygpt.

I am not saying manager is not important. In my working place, I am merely a manager, my boss is the true leader. Obama can be a good manager, but you might need person like McCain as the leader.

You are right that Proverbs 30 was actually saying of Agur not Solomon, I was wrong as though all proverbs were from Solomon.
