I think that being passionate about something makes it easier for people to believe in what it is that you have going on. On top of that, when I explain mathematics, I talk about its beauty and I am expressive in the appeal that it has to me. Other people, especially in prisons, see this ..thing that is described to be intellect made purely aesthetic. When people see how it reflects inside me, it makes them want it as well... or so I am told.
If there's one thing I want to see happen as a result of my passion, it is to show other prisoners that they can live a completely different life. The type of life as a productive member of society. If my passion has the power to affect the rate of recidivism, I will take that as a small contribution to justice being served.
