This document discusses the differences between contributors and non-contributors. It states that non-contributors focus on their past accomplishments and failures in defining their identity, while contributors focus on what they will achieve in the future. Contributors are always willing to take on new challenges and find ways to benefit both themselves and others. In contrast, non-contributors are only concerned with their own self-interest. The document advocates shifting from seeing oneself as a "victim" to a "creator of one's own destiny" in order to develop the mindset of a contributor.
