What makes a leader?

Let's see here, what makes a good leader? Is it intelligence? In my opinion, no. While intelligence is needed  to critically think and analyze how to deal with situations, Basing leadership on simply how clever they are might yield disappointing results. First off, it depends on what kind of intelligence they have. I myself make no claim to understand intelligence in the slightest, but there has been theorized to be multiple forms of intelligence by others in the past. 

A good leader should be empathetic to others and an excellent listener and thinker. Good social and verbal skills would be a plus.

In my group, I'm almost ashamed to say that since we didn't know what being a leader entailed, we simply selected Vinh, who eagerly volunteered to be the leader.
