Rachel, I love what you said about being thoughtful about what you publish. That’s a great mindset. As you begin to write on Medium, you’ll be tempted to compromise on that philosophy, but don’t give in!
And btw, I would challenge your idea that you don’t have “your ducks in a row” yet to write. The beauty of writing is that as you do it, it comes easier and easier. Daniel Pink says, “Writing is an act of discovering what you think and what you believe.” I firmly believe that. If you were to begin crafting a story tonight, I’m sure you’d realize that you truly do have something to say and that those ducks are lined up more than you thought. ;-) Not to say that the story will come easily (they often do not), but I bet you are more ready than you think.
You may find the story below useful in your journey. Thank you for your comment, and I wish you the absolute best with your writing.
