Ping to an example of Scientology from our earlier discussion.
I was one.
I was not a star nor did I strive to become one. I was a journeyman performer for much of 25 years. I was a regional actor (successfully) working just about every legitimate stage, east of the Mississippi.
I toured in over 200 separate productions.
I received my Classical Training on the road, not at an accredited Artist's College....but I kept got getting callbacks.
One of the things I do know. There is no politics before the stage lights come up....nor is there any apparent, during the grueling rehearsal periods...the cue to cue...or the damn stressful Opening Night!
The national and international success that we are commenting about...are experienced by a very select few.
The people in question...are the lucky few, who have for reasons..of pure luck..and looks...hit the top of the pyramid. Such is the same in any industry.
Their luck has nothing to do with intelligence.
