Do not skip this one.
Write the first paragraph of your book this weekend. Not the whole chapter. Not the outline. Just the first paragraph.
Start with the moment everything changed. Put yourself back in that room, that hospital, that car, that conversation. Describe what you saw. What you felt. What you thought was about to happen.
That paragraph is the door your reader walks through. Make it real.
Post it here when you write it. Even a rough draft. The community will celebrate it with you.
