Self-help ✦ Penny’s Take
Productivity is Power
Hillary Rettig · 2021
63/100
👎 Skip It
Same strong bones as Rettig's other title here — named techniques, real compassion for students who don't thrive under grind culture, genuine equity focus. But this and 'Power is Productivity' look like the same book republished, and the date doesn't check out, so I'd point you to one or the other, not both.
