Determination is a fine thing. There is much to be said for knowing what you want and then setting out to get it, regardless of obstacles that may lie in your path. Yet some doctors and psychologists might disagree with this. They could point to the high blood pressure that many control freaks seem to suffer from - or the broken marriages that often ensue when one partner is overly dogmatic. There is also a lot to be said for fluidity and flexibility. These are the only qualities that you now require to do well in life.
