The Elements of Harmony represent virtues which support a powerful force in our world. It is not the virtues that are flawed, but ponies, and even our perceptions of ponies. Ponies, and I assume humans (given your behavior) all have good inside of them, but sometimes we don't stay true to that good inside of us, or it doesn't show as clearly as we'd like. What the Elements require the most is that we can understand that virtue within our hearts, and we do try to strive for that virtue in our daily loves. It's okay if we can't always manage it, the effort and the light in our hearts are channeled by the Elements toward a goal.
