"If I could just find the right publisher/editor/agent."
In 1997, I taught at the Greater Colorado Christian Writers Conference. One man had a lengthy manuscript and asked me to look at it. I thought he had a few good ideas but nothing particularly original. It wasn't different from anything I'd read many times.
I told him but he didn't listen.
"If I could just find the right editor, I know my book will sell." Those were his final words.
Afterward I walked toward the dining room and a woman came up to me and said she saw me looking at the man's manuscript. Before I could comment, she said, "He comes every year with the same book. He hasn't changed a word. He's convinced that if he keeps trying he'll find the right publisher."
Since then I've met several others like him. Their attitude says they don't want to grow, don't want to work hard to improve the manuscript, and they're satisfied with what they've written. They're usually the ones who cry about publishing being a closed group and "common people like me" can't get inside. It doesn't seem to occur to them that good writing opens many doors.
To find the right publisher become the right writer.
