In theory, many things sound easy, but reality/practice is something quite different. What we humans want is to live, and to live means to experience things around us, good and bad. If we took every experience from others how could it be called life?

We all know that we should make plans for the future, but sometimes (rarely or more often) all plans fall through the cracks and we are forced to start from the beginning. As Woody Allen said, "If you want to make God laugh, tell him your plans.". So I understand people who feel casual, without any big plans just living their life. Everyone has a right to their own life and I doubt that anyone can say how best to live, everyone has their own wants/hopes/needs/etc.
