Bonni Goldberg talks about this in Beyond the Words.
"I often check my motives before I share by asking myself, what I want to get from making a given piece public. I know it's not the right time if my "want" list includes items such as empathy and understanding from my audience or their appreciation and attention rather than the opportunity to voice something I care about or to celebrate what moves me. As you take time to become aware of your motives to go public, you'll notice when it will be more nurturing and respectful to your Writing Self to wait" - Beyond the Words, p. 170.
Goldberg has opened a vein of truth here! I can think of times when I posted something, waited on tenterhooks for a response and when there was none, felt deflated and a failure. It pays to be aware of why we want to share something, and when is a good time. Sharing out of neediness can be a dangerous thing to the health of our creative selves.
