BookCast: Limitless by Jim Kwik

What if the world’s #1 brain coach wrote a book that’s better suited for someone else than you? The ProductivityCast crew puts Jim Kwik’s Limitless under the microscope, and their verdict might save you 12 hours of listening time (or not! πŸ˜‰). Today, we’re doing a book review of Limitless: Upgrade Your Brain, Learn Anything Faster, and Unlock Your Exceptional Life by Jim Kwik. (NOTE: We recorded this book review before Kwik published his latest edition, Limitless Expanded Edition (December 2025); however, at least for Ray, who had a chance to read the latest version, his opinions shared in this episode haven’t changed.)
