Not because it might hurt. No, because it will. Growth comes from many places, few of them help your craft better than enough hurt from being vulnerable.
It sucks. As someone who tries to put himself there often, I cannot come up with a cure for the feelings of self-doubt and shame that come with being left stranded.
Even so, after I deal with it, nothing replaces the feeling of knowing that I have radically changed. The person that went to sleep woke up evolved.
