My kids took part in the Set a Good Example Contest and really enjoyed themselves.
This contest is based on The Way to Happiness Book written by humanitarian L. Ron Hubbard. It is a common sense moral guide based on secular principles.
Sponsored by the Concerned Businessmen's Association of America, thousands of children have participated worldwide, and learned how they can help improve conditions in society.
This was a very good activity for my own kids. I highly recommend it to other parents!
