Not totally, I mean. Oh, I've met people who were CEO's of major corporations, at the top of the field in their academic discipline, or ward winning in their art. But there was always some accompanying struggle, some failure in their lives. They neglected their families to their ruin or they picked up some debilitating addiction or they lost everything in a foolish gamble. I've never met a total success, nor have I met a total failure.
Every person is successful at some things, a failure at others.
And it seems to me, character is shown more in how people handle their failures. As successful as Naaman was, he couldn't protect his health. He contracted leprosy. He denied it to himself as long as he could, but the skin lesions and deformed fingers were getting worse. Then he tried to hide it.
