The only way to avoid jumping straight into harm’s way is to learn how to get outside yourself and view your own public image through the eyes of readers, followers, colleagues, and friends. Silently noticing what other authors do wrong and right can help. Friends and family aren’t likely to give you honest criticism, because they all love you and fear ruining their relationships with you.
We’re living in a moment when genuineness, transparency, and humility are valued more than poise and sophistication, but cultural preferences eventually will change. They always do.
