He is a wise man who does not grieve for the things which he has not, but rejoices for those which he has.

“We have all experienced times when our focus is on what we lack rather than on our blessings. Said the Greek philosopher Epictetus, ‘He is a wise man who does not grieve for the things which he has not, but rejoices for those which he has.’ …

“Regardless of our circumstances, each of us has much for which to be grateful if we will but pause and contemplate our blessings.”

Thomas S. Monson, “The Divine Gift of Gratitude,” Ensign, Nov. 2010, 88.
