I have a good friend whom I admire for her energy, curiosity about life and optimism. She is well into her eighties with an unbroken zest for life.

A while ago, she told me the secret for her positive attitude: “When I get a box with a variety of chocolates, I will eat only one per day. On the first day, I will select the one that I like best. The next day, I will take the best of the remaining, and this I will repeat every day until all are gone. This way, I get to enjoy every day just the best of all my options”.
