Here's why:
* Autobiography is a comprehensive account of a person's entire life, from birth to the present.
* Memoir focuses on a specific period, theme, or event in a person's life. It allows the author to explore a significant experience in depth and share their personal reflections and insights.
For example, a memoir might focus on:
* A specific journey, like a cross-country road trip
* A significant personal challenge, like overcoming addiction
* A pivotal moment in their career, like landing their dream job
* A defining relationship with a loved one
While memoirs can be part of a larger autobiography, they can also stand alone as individual works.
