It's interesting to think about the nuanced distinctions of rituals, habits and routines. I would argue that thriving work groups create and celebrate rituals. 

I like the idea that routine and ritual are both habits. Routine comforts us and ritual revitalizes us. Routines bring order from chaos. Rituals celebrate connections from solitude. The intention we bring can make anything a ritual or routine. Routines have pragmatic value. Rituals bring meaning to repeated actions. Doing anything mindfully and with gratitude turns action into a ritual.
