I agree that we need to reinstitute meaningful ceremonies to mark important milestones in our lives. The ceremonies that our modern culture does still hold on to have been over commercialized and devalued from their true meaning.
Community should play a vital role in this ceremony building. We also must find a way to make this viable in the current techno - culture in which we live. Our definition of community has broadened beyond the circle of humans in our physical vicinity.
But until we can reconcile this, We should create our own ceremonies. The question of where to begin: Just have fun. It is a celebration after all.
