I truly believe that there is no eternal business. The world is changing constantly. It is causing the market changing so there is no reason why the business has to stay the way it is. Change or die.
As business leaders we need to realize that failures are normal and natural part of the innovation. Companies that succeed in launching new products have 35% failure rate. The leader has to be wise enough to accept, understand and be brave to take risks in order to achieve new success.
