Polymath: Master Multiple Disciplines, Learn New Skills, Think Flexibly, and Become Extraordinary Autodidact Book by Peter Hollins

Polymath: Master Multiple Disciplines, Learn New Skills, Think Flexibly, and Become an Extraordinary Autodidact by Peter Hollins (published in 2020) is a practical framework designed to dismantle the myth that you must specialize in a single career path to succeed. Hollins, a human performance researcher, argues that modern success belongs to the "Pi-shaped" or T-shaped individual—someone who builds functional competence across diverse domains to become entirely irreplaceable.
