You know you can't be a writer unless you have your work reviewed by other people. You know this. No writer can make their work shine as brightly as it can without the assistance of others. For those attached to large publishing houses, you are lucky enough to have a skilled editor going through your work for you, pointing out what could be better, or simply what needs to go in the trash. For the rest of us, we have to hire an editor, which is expensive—and frankly, not a good use of money with a first, or even second, draft.
