both of these things, in my opinion, come hand in hand. The one who is smart, usually has a strategy as well. For example, Napoleon Bonaparte, was one of the best known strategician's, but was he smart? Of course he was, just look how he influenced entire France with speeches that inspired a revolt against the government. He had this natural ability, which many would cool smart (and I agree), to convince people and make them do what he wanted to do. So, both are necessary if you want start something great
I have to disagree with your view on Napoleon
I don't know whether he was smart or not, but I don't think that he was one of the greatest strategists. Had he really been, he wouldn't have ended like he did, in captivity and isolation on the island of Saint Helena. Nevertheless, you raise an interesting topic of how the ego can interfere with one's ability to stick to their strategy (which seemed to have massively plagued Napoleon). In other words, just being smart and strategic is not enough. You should also keep your ego bridled at all times
