Write a narrative story about how you failed to do or failed to achieve something. Describe what you tried to do, how you failed and what you gained/learned from it.

So...

Explanation:

You could think about what many people fail in life at -tests, a task set by your teacher, achieving your dream, losing someone you love...

Then you can expand on this, thinking of the details of your story e.g. who is the person you lost, what did you not achieve when failed to do something.

Think about how you might of learnt from the experience- like "I learnt that I can't always win everything." or something...

Hope this helps!
