How can we keep forgiveness initiatives going in schools and social groups, such as correctional institutions?

In my book, The Forgiving Life, I talk about the free will, the good will, and the strong will. Rarely is that third kind of will—the strong will—discussed in philosophy.  A key to planting forgiveness and reconciliation, after initial enthusiasm identifies these as vital to the human condition, is the strong will. This needs to be fostered. Otherwise, we have continual patterns of: 1) interest shown, 2) some initial activities to introduce the moral virtues into a school or social group, 3) only to be met, over time, with the fading of the initiative.  So, an important question is this: How can we foster the strong will so that the programs continue for a long time?
