Writing a play.

I would love to write plays that are produced in theatre and one day be recognised as Australia's next Lawler or Williams or realistically be known more as myself. but how to achieve this, I wondered to myself as I wrote a play whilst I was on a plane to America, (one must occupy themselves somehow on these long haul flights) what sets a good play apart from a bad one? Of course character, relationships, tension, subtext etc will all play a significant part, but is there an easier way to know how to captivate your audience? Surely many thoroughly thought out plays can fail whilst some others that have been knocked up and become surprise successes with the playwright never being able to recreate that success for the simple reason he can't identify the wining formula. Shakespeare and Checkov wrote very different plays. Both are held in very high esteem . Shakespeare is timeless and connects with audiences of all ages. One would struggle to convince me that Checkov is the same. Perhaps this example would be better served by two examples more similar in style but a playwright should really write for the ages. After all is there that much pride to be taken by being a one hit wonder? Your thoughts, Ladies and Gentleman.
