Have you ever had one of those dreams where you find yourself in a public place without pants? The human reaction to embarrassment can be quite strong, and dreams like this are often simply the subconscious mind's way of working through those fears.
Sometimes sharing our creative work can make us feel similarly vulnerable and afraid. What if no one likes it? What if it's completely ignored?
As a writer, it's critical to know when to share your creative work. In the early stages before the polish has been applied, very few people will be able to see the potential of your story. But feedback prior to final publication can be extremely valuable.
I generally share my work with supportive friends and family once the manuscript text has been drafted, rewritten and edited. That way they can read it while I finalize the formatting and cover art. If they notice any errors, I can correct them in the final version.
Some people keep their work hidden from everyone. They bury their talent, fearing what others might think.
Don't be one of those people. Don't wait for perfection before sharing something you've made. Focus on "good enough" and put yourself out there.
