Weakness and strength are necessary for balance. No one or nothing is only weak or only strong. But some of us overlook our weaknesses, and even deny that we have them. That can be dangerous, because denying there is a weakness is in itself a weakness. Likewise, accepting that we have weaknesses becomes a strength. And by the same token, overestimating strength is a weakness. You should not be blinded by your strengths. The feeling of strength is not the same as having strength. Neither should you ignore your weaknesses. Know them well, too.
