At Worldcon, Brighton, in 1979, I was privileged to sit among a small group of unpublished writers while the great Alfred Bester dispensed his wisdom. (He looked somewhat like Edward G. Robinson in Soylent Green.) One of the things he talked about was the necessity of sending your stories out into the world. Like kicking your children out of the house when they're grown up, he said. It hurts but you have to do it.
The context was mostly about sending unsolicited work into the publishing world - when you're delivering to a contract, it's more like relief.
I just emailed POINT to superstar editor Marc Gascoigne. Whew!
