All too often ideas....

.....implant themselves into our heads.  We then let them ferment and believe that things have to be a certain way. When they work out as we want them to, we celebrate. When they don't, we feel disappointed. So deeply attached do we become to these expectations that we cannot bring ourselves to question their importance. We are not interested in any other view of reality. Success equals what we wanted to happen. Failure equals something else.

Sometimes, by avoiding that attitude, we can experience a very pleasing development.

The radical of one century is the conservative of the next.  The radical invents the views.  When s/he has worn them out, the conservative adopts them.  (Mark Twain)
