Who Not How by Dan Sullivan and Benjamin Hardy presents a transformative approach to achieving personal and professional goals by emphasizing collaboration over solitary effort. The central premise is that instead of asking, ‘How can I accomplish this?’ one should ask, ‘Who can help me achieve this?’ This shift from a ‘how’ to a ‘who’ mindset can lead to greater efficiency, freedom, and success. I also recommend their book 10x is Easier Than 2x, and my all-time favorite is Nine Lies About Work from Marcus Buckingham.
