Tackle it one step at a time:
1. Find a topic you're passionate about.
Or, if you have one already, study the prompt to understand what is expected from you.
2. Create an outline.
If it's your first time writing such an essay, choose chronological order when telling your story.
3. Follow the outline.
Try to paint the complete picture for the reader and keep the story's moral in mind.
4. Edit or proofread your essay
several days after writing it ‒ you need a fresh perspective. And if it seems like a lot to take - we'll be happy to help you.
