Harrison claims, "You keep on going until you get it as close to being right as the time and patience of others will allow."
I like that he allows for the variables of time and patience. That works for me. Before ever submitting my work to contests or agent consideration, I always make it the best I can at that time. But if I learn something at a conference workshop, I'll immediately revise other books so that they always reflect my best effort. It's as close to being right as I can make it given my current skill level and life circumstances.
The more I write, the more I realize that though I may be the author, my stories are really collaborative efforts. I can only take it so far, and then a critique buddy or friend offers a terrific idea for a plot twist or brilliant characterization moment.
Truth be told, I'm instantly thrilled and annoyed that I didn't think of it since it's my book and I know it and my characters so well, but I'm over the jealousy in a nanosecond and thrilled that someone offered me a way to make my work better. No limit for better.
Not being open to No Limit For Better, in my opinion, breeds mediocrity and a continued unpublished status I don't particularly desire, so . . . I'll try to remember this when I get my next critique and hear something I might not want to hear. No limit for better.
