The secret to a happy life is revealed by Geoff (87) from Glebe, NSW: Be sincere and truthful in everything you do. You cannot be unhappy when you hold fast to these two principles, because you will not gossip, lie, do anything to hurt someone else, be manipulative or mean. Even if you tell someone a truth that may hurt them, your sincerity in the motivation to do so will cancel the hurt very quickly. Living by these two virtues will enhance your life and you will be happy.
