Even if you had done it, you may not have had access to exposure or distribution so anyone would have seen it.
A great deal of life is about access, connections, luck or fate.
A great article I once read by Fran Liebowitz (sp?) was a rant about access. It was along the lines of actors/actresses who have famous parents, and their stating that YES, they got their foot in the door because of their parents, BUT it was their talent that got them hired regularly in their TV series.
And Liebowitz's claim, that the foot in the door is actually the only hard part. The actual acting 90 percent of the population could do it.
Remember she wasn't talking about great actors, but about the shlock acting that is regularly regurgitated on TV.
I wish I could find the article again.
