The document discusses how to motivate and engage volunteers in non-profit organizations to continue volunteering beyond the typical 2-3 missions. It states that money is not a motivating factor for volunteers, as their work is not paid. However, volunteers often lose interest after a few missions. To keep volunteers coming back and doing more, the document recommends using intrinsic rewards like creating competitions, publicizing individual profiles and achievements, leaderboards, and badges to recognize certain behaviors and milestones.
