It is generally believed that as we go through life we don't really change. We just become more of the same. Bar- ring the usual exceptions that, as we say, prove the rule, when  we look around us as the years go by, this seems quite valid.  On the whole, people don' t change, and most of us strongly  resist change.

Nevertheless, all our worries and wars are based upon change. We fear that something will happen, or we fear that it  won't; so we fight to prevent change or to speed up the pro- cess. But whatever we do, change is 100 percent guaranteed.  The only question is its rate. Slow change we interpret as  evolution, fast as revolution. Changes are the epitome of Un- knowns—the greatest of fear generators.
