We're all searching for supportive (but not coddling) and careful readers who respect our ideas yet offer good ones of their own.
Where to find this kind of feedback? Some people get it from a writers group. Some get it from workshops and classes. Some exchange writing with a feedback partner. Whatever works! As long as the comments open you to new insights, keep you writing, keep you enthused and engaged with your own writing, they are useful.
But all of these methods are based on vulnerability--sharing ideas and images and attempts with people who don't see the full vision you do. And most of these employ something called the "workshopping method," which has its pros and cons. How do you set yourself up for success? For the best possible outcome with the least risk? It's not easy--but there are definitely things to embrace and things to avoid when workshopping your writing.
