Quote of the day by Diane Keaton , “Babies laugh three thousand times a day. Adults twenty, if we’re lucky,” is about the difference between childhood and adulthood. Babies can respond to small things with laughter. Adults often spend more time thinking about work, money, responsibilities, failure and other worries. The quote uses this contrast to explain how people can lose their natural sense of joy as they grow older. Keaton included the thought in her 2014 book Let’s Just Say It Wasn’t Pretty, a collection of essays about aging, beauty and self-acceptance. The message is to notice simple moments and make room for laughter.
