In 2016, aged 57, Lucy Kellaway quit her prestigious, full-time job as a journalist at The Financial Times to become a trainee teacher.

Around the same time, she also left her husband of 25 years, with whom she’d had four children, moved house and stopped dyeing her hair.

Lucy wrote about her experiences in her book, “Re-educated: How I changed my job, my home, my husband and my hair,” and co-founded the charity Now Teach to encourage older professionals to step into the classroom and change their lives in the same way hers was transformed.
