There is incredible power in words. A sincere compliment can have an effect decades after it is spoken. Here is a quick story from Joseph B. Wirthlin:

"One day, when I was in college, a man seven years my senior congratulated me on my performance in a football game. He not only praised how well I had done in the game, but he had noticed that I had showed good sportsmanship. Even though this conversation happened more than 60 years ago, and even though it’s highly unlikely the person who complimented me has any recollection of this conversation, I still remember the kind words spoken to me that day by Gordon B. Hinckley, who would later become President of the Church."

What will you say today that someone will remember 60 years from now?
