Turns out that we got it all wrong when it comes to stress. I first found about the book through her TED talk titled "How To Make Stress Your Friend". Also you might have heard of Kelly before through her first book "The Willpower Instinct" which changed the way we think about willpower. I can safely say that The Upside of Stress is as groundbreaking as The Willpower Instinct. For me the most interesting part of this book was the research with professional athletes where they realized that these people were actually A LOT more stressed than the beginners but they used their stress to fuel optimal performance. So it comes back at that ability to utilize stress to enter a state of Flow, and even smaller amounts of it can be beneficial when learning or performing any skill. Another interesting part of the book is the health consequences of framing stress as harmful vs helpful: As the author says "this could even mean the difference between having a heart attack at 50 or living into your 90s". The big idea of the book is that avoiding stress can hurt you physically and mentally, whereas high stress can be good for you to achieve happiness and great performance. And by simply re-framing the stress as "excitement" you can turn it into a powerful asset on your journey of becoming the best version of yourself. I'd highly recommend you to check this book out if you feel like you have to "deal with stress" a lot in your life and that stress is holding you back in life.
