As a new author, I try hard to make sure my written words convey the story in a clear and compelling way. That can often make the process longer due to rewrite after rewrite, but I've learned from my marketing and graphic design background, that I will know when it's right. Developing an ability to see/hear/feel when it's right is important for the creation of a great story, a great song, or a great painting... and it allows you to keep your sanity.
The lesson: Trust your intuition as a writer. Don't hold yourself back. You'll know when it's right.
