" Being confused about reality, we naturally feel insecure and are nervous and tense. We tend to make such heavy ordeals out of everyday things in our life, such as driving to work or putting the children to bed, that we feel constantly stressed. Of course we need to be concerned about life and take care of our responsibilities, but there is never any need to handicap ourselves with compulsive worry and chronic anxiety. They only prevent us from effectively dealing with life. They certainly do not lead to happiness and peace of mind. To paraphrase the eighth-century Indian master Shantideva, “If there is something difficult in life that we can change, why be upset? Just change it. But if there is nothing that can be done, why be upset? It doesn’t help. "
