Although images of perfection in people's personal lives can cause unhappiness, images of perfect societies — utopian images — can cause monstrous evil. In fact, forcefully changing society to conform to societal images was the greatest cause of evil in the twentieth century.
We create our own unhappiness. The purpose of suffering is to help us understand we are the ones who cause it.
All blame is a waste of time. No matter how much fault you find with another, and regardless of how much you blame him, it will not change you. The only thing blame does is to keep the focus off you when you are looking for... reasons to explain your unhappiness or frustration.
In this life, we have to make many choices. Some are very important choices. Some are not. Many of our choices are between good and evil. The choices we make, however, determine to a large extent our happiness or our unhappiness, because we have to live with the consequences of our choices.
