Correct answer
Explanation
Neil Armstrong is correctly attributed as the author of this quote about not wasting heartbeats. Armstrong (1930-2012) was the first person to walk on the moon and lived life with urgency. This quote reflects his approach to life's limited time. Mohandas Gandhi, Michelle Obama, and Mother Teresa are not the source of this quote, which captures Armstrong's test-pilot philosophy of living fully.
