A Letter To Myself - In cleaning homes for 40 years, volunteer Fion Phua says the underprivileged help her

 Fion Phua, founder of volunteer platform Keeping Hope Alive, has been volunteering since she was 16. For more than 40 years, she's witnessed severe cases of hoarding, including one where someone hoarded toilet paper. But she doesn’t tell the people she meets she’s there to lend a hand – instead, she asks them to help her be useful. She shares her story with Joel Chua.
