Alexander the Great's nickname may not be entirely accurate. He seems to be an ordinary guy for the most part. The only thing "great" about him is his ambition. To do what he did, and to do it at such a young age is clearly the result of some kind of superhuman ambition. If Alexander lacked this great ambition, he probably would have wanted to turn back when his troops did. But he prusued onward regardless. So, he was just an ordinary person, but his ambition and courage were extraordinary.
