Most influential book you’ve read

“To Conquer the Air” by James Tobin. One of the most inspirational books about inventors and the process of invention. It’s about the Wright Brothers and the invention of flight. With very limited training and financial means, but with much grit and determination, the two brothers forever changed the course of human history.
