Sad but true. Having spent a great many years in mechanical design I've come to the conclusion there are 3 stages to a "good" idea...
1) It will never work
2) You're crazy
3) Next time you need another "good" idea like that, come and see me
Even more bothersome, for those who recognise and pursue good ideas they are soon labelled as rebels, trouble makers etc (& worse) in the group-think environment despite a history of successful accomplishments.
Somehow we muddle thru, but you have to wonder where we would be if it were not for those who will pursue good ideas, however & whatever it takes, the entrepreneurs.
