You can't tell how deep a puddle is until you step in it ~ Unknown
When I started writing A Place to Call Their Own four years ago, I had no idea of all the support available to new writers. I expected to go to the public library, check out a few books on how to get my manuscript published, and be done with it.
I am still amazed at all the support and resources available for new writers. The explosion of the social media in the last few years has helped this tremendously. I love having my group of Facebook friends and people I follow on Twitter posting articles of interest to help me in my quest to become a published writer.
So whatever goal journey you're on, just get started. After you get going, examine all the information you might be able to find on making your dream a reality.
