This book is the ultimate resource for anyone starting a business or trying to change the world in a meaningful way. It's not a matter of if, but when challenges, fear and doubt arise when doing impactful work. Ryan's book is the roadmap for not just clearing those hurdles, but pole-vaulting them in a bedazzled onesie​ with a smile on your face. Great stories showing how different figures in history have overcome adversity, including an awesome story about Thomas Edison.
