Vijay Anand discusses where ideas come from and the differences between inventors, entrepreneurs, and scientists. He explains that great ideas result from both rational thought and gut feelings. Breakthroughs are born when different fields collide. To cultivate new ideas, one should embrace constraints, break patterns, ask "what if" and "why not" questions, be human-centered, be willing to polarize and prototype over expertise. While ideas are just the beginning, execution is what ultimately determines success.
