How often do you think you complain in any given day? Five times? Twenty? Do you even know?

According to pastor Will Bowen, complaining has become such an automatic response to daily setbacks that people don’t even realize they’re doing it. That’s why more than a year ago he set out to remind his parishioners that in order to live a happy and prosperous life, you have to stop complaining. After giving each member of his congregation a purple rubber bracelet emblazoned with the word “SPIRIT,” he challenged them to stop complaining for 21 days.

It took Bowen three months to stop complaining; other churchgoers took much longer. Since that summer sermon, God has been very, very good to Will Bowen. Local news organizations picked up his story and Bowen wrote a book, now in its seventh printing. He went on the “Today” show and then on “Oprah.” His church has mailed 5 million purple SPIRIT bracelets all over the world and continues to do so at a rate of 25,000 to 50,000 per week.

While Bowen advocates for eliminating complaining entirely, Dr. Laura Schlessinger argues in her new book, “Stop Whining, Start Living,” that some things are worth complaining about–in which case, make it short and move on. Does complaining ever have value in society, or should we, like Bowen, aim to purge it completely from our lives?
