Alan Ayckbourn has a life in theater such as we don't see much any more. He acted in his youth, he still directs, he runs a repertory theater in his home town of Scarborough (it does his plays, but others too, and it tours the region), and he keeps writing: 78 plays now, which averages to about one per year of his life.

Not every play is a winner, but that's the inevitable odds of any prolific creator. To paraphrase a quotation whose source I can't immediately recall, we wouldn't have the great 30 without the other 50.
