Increasing Volunteer Engagement

I’ve been racking my brain lately about the Pareto principle and how to engage the 80%. While I have come up with no concrete solutions… I did realize that I speak about the 80/20 principle as fact. (Which may be in economics (A topic I am completely unqualified to discuss.)) However, in terms of volunteerism and participation, the 80/20 rule is more perception than reality.
