Six years ago, at her home in Morristown, New Jersey, Barbara Hill's side hustle the spirit animal walked through her front door. “She was absolutely ancient,” Hill recalls. “I was like 61 or 62, but this woman was almost a hundred or something. It was definitely a retirement job for her.”

At the time, Hill had a big business selling web-based video conferencing and wasn't planning on retire anytime soon. She had taken out a home loan on her home and the bank had sent a loan underwriting agent to her home to walk her through the paperwork. She was the ancient lady. “It just struck a chord with me,” says Hill. “I asked her a million questions. Turns out she was doing this to supplement her social security.”
