- The Polymath by Waqas Ahmed. This one directly discusses polymathy in history, and how our "natural state" really is of that of the polymath, not the specialist. A nice book that helped me get past some mental blocks and really embrace learning whatever it is I'm interested in, without reservations on what others may think about such "distractions".
- The Creative Way by Rick Rubin. This masterpiece is written by a legendary musical producer who has probably worked with one of your favorite Western musicians at some point. His Zen-inspired approach to creativity and acceptance of ideas, wherever they may come from, is an essential tool in any polymath's toolbox.
- How We Got to Now by Steven Johnson. I really enjoyed learning how the world-changing inventions that we take for granted were often invented by creatively gluing together wildly divergent ideas, to ultimately make something that appears deceptively simple.
The key takeaway for me is that anyone and everyone can be a polymath, with the correct attitude. Learning is not a skill reserved only for the most intelligent and capable - everyone is capable of learning anything they want. Some people may be more naturally skilled, but that doesn't preclude the rest of us from participating.
