(Continue reinforcement of these points. Ask them for examples of paradigm shifts.)
Two key statements are:
1. Past success guarantees nothing if a paradigm shift occurs. The example of the Swiss watch makers when impacted with the quartz and digital movements illustrated this perfectly. The electronics industry goes through this constantly.
Who can think of any other examples?
2. What is impossible today may be the norm tomorrow. What are some things that are being done today that were believed to be impossible not so long ago?
If we are not challenging ourselves constantly in dealing with the impossible, then we might be on the outside looking in when the paradigm shifts.
