It is sad how often we try to determine our own value by how much we feel that we have accomplished. There are several problems with this assessment. First, we tend to focus on this evaluation most when we feel the least accomplished. When things have not worked out as hoped in our lives we begin to reflect on our own apparent worthlessness.
The second problem is that the more often we conclude that we are worthless the more likely we are to live as if this is the case. Why try when nothing we endeavor to accomplish works anyway? This notion can be debilitating and can keep us from making progress toward our goals. Hope is one of our primary motivators. With the loss of hope goes the confidence that with time and effort our situation can improve.
