But, if you love your story and have prepared it reasonably well, you will surely give pleasure to your listeners and yourself. And, each time you tell the story, you and your story will improve. If possible, tell your story first to friends in a small group. As you gain confidence, perform for larger, less intimate groups. Before long, you'll think nothing of telling to a large room full of strangers.
Storytellers have their own styles, differing widely.
If a suggestion here doesn't fit your idea of how you want to tell stories, ignore it. Don't be afraid to try something different, if it feels right. A good storytelling space is comfortable, intimate, and free of distractions. Give your listeners the full force of you. Aim your voice at the back row.
