Trust in yourself.

Believe in yourself.

Have faith in yourself.

Trust your readers will feel your impact.

Believe your readers will benefit from your story.

Have faith that you're making a positive change in the world.

Doubt may creep in.

Worry may overtake you.

Fear may freeze you.

Follow your muse, your intuition, your gut feeling.

Ground yourself. Know yourself. Empower yourself.

When you write, write from your heart, your truth, your joy.

Keep at it—whether through an impassioned plea or a steady, quiet thrumming.

That is how you will make an impact.
