We each come by the gifts we have to offer by an infinite series of influences and lucky breaks we can never fully understand.

I have no doubt that tremendous value comes when people act quickly on the impulse to give. No drive has more positive ripple effects than the desire to be of service. There are lots of resources each of us can pull from our safes to share with others time, attention, knowledge, patience, creativity, talent, effort, humor, compassion, she added.
