Service
Service is a responsibility. We have obligations, not formal and contractual, but to me inherent, that indicate that we have a responsibility of serving others, of helping where and when we can, of paying it forward. You need not be a philanthropist or a community organizer. You could simply call on a neighbor in time of need. Hold open a door. Caretake for a loved one. Treat the opportunity of small, and big, service work as a solemn charge that you, as part of humanity, have.
