Human beings have an infinite capacity for two things: giving and love. Do you think Mother Teresa ever ran out of love and care to give to the sick and the destitute? At nearly 85 years of age, and with a weak heart, she was still out there giving; traveling and speaking, caring and working as she had been every day since she was a novice. Thats because giving nourishes and replenishes the giver. Taking depletes us and burns us out.
