It isn’t that happy people have no sufferings; it’s just that they are not manipulated by suffering. It’s inevitable to encounter suffering in our lives, but suffering isn’t that terrible. It is worse when our hearts have betrayed ourselves and become an accomplice to pain/sufferings. Manage your emotions by forgetting the unhappy happenings: listen to music, look at scenery, talk things over, do some work, go for a walk, or visit a friend. Finally, perform these tasks happily with a smile.
