The LizyT show with Children's Author Sheila Mitchell?
She is a retiree who did not give up on her dream to publish a book. She published her first children's book this past September called, I Love You, Grandma! She has received many positive reviews on her book.
Possible topic(s): Life after work. For some people retiring is daunting (what will my place be in society without work?) but she is a perfect example of it being an exciting new chapter in your life. She also can discuss her journey through publishing her first children's book.
