Vitality in daily life

Watch a child at play. They seem absorbed in a source of vitality and joy drawn from simply being in the moment. As the child grows into adulthood they seem to lose connection with that source of vitality. Even though they may still experience extraordinary moments of vitality, ongoing connection is often hindered by the pressures, routines, responsibilities and challenges of everyday living. What is the source of vitality in daily life? What hinders our connection? What assists our connection?
