Grit is an investigation into the importance of determination and perseverance for success. Society tends to focus on the importance of natural talent. We observe athletes, musicians, and academics performing at the highest level and assume they are there because of lucky genetics. The author accepts that genetics play a part in achieving success, but she suggests that effort is twice as significant. The book provides guidance on how you can encourage grit, maintain grit, and intelligently apply effort to improve your chances of reaching your goals.
