Self-help ✦ Penny’s Take
21 Side Hustles You Can Start Now
Henley Griffin · 2015
55/100
👎 Skip It
Henley Griffin actually has a track record earning online income since the late 2000s, and this quick 68-page rundown of no-cost side hustles has a clean, sensible premise — using what you already have to make extra money. It's a 2015 book though, so some of the specific tactics are almost certainly dated now, and I couldn't find anyone who's independently checked how well the advice holds up in practice.
