The Alchemist by Paulo Coelho
When someone sees the same people every day, as had happened with at the seminary, they wind up becoming a part of that person’s life. And then they want the person to change. If someone isn’t what others want them to be, the others become angry. Everyone seems to have a clear idea of how other people should lead their lives, but none about his or her own.
The secret of happiness is to see all the marvels of the world, and never to forget the drops of oil on the spoon.
