This book is about embracing pain be it physical, mental, or emotional. This book is a life journey of David Goggins and how he was able to master his mind by defying the odds.
Our brain wants comfort it doesn’t want to do the work that is why we form habits so that the brain can work in autopilot mode. While habits serve a huge purpose in our lives but the brain tends to follow the path of least resistance in every walk of life, which leads to the formation of self-destructing habits. Which hamper our ability to realize our potential.
To achieve anything meaningful in life we need to sacrifice something, take the pain, and delay the gratification. Always trading short-term comfort for a long-term uneasiness is the worst deal you can make to yourself.

Major Takeaways :-

“I thought I’d solved a problem when really I was creating new ones by taking the path of least resistance.”
“It won’t always go your way, so you can’t get trapped in this idea that just because you’ve imagined a possibility for yourself that you somehow deserve it. Your entitled mind is dead weight. Cut it loose. Don’t focus on what you think you deserve. Take aim on what you are willing to earn!”
“We all need small sparks, small accomplishments in our lives to fuel the big ones. Think of your small accomplishments as kindling. When you want a bonfire, you don’t start by lighting a big log. You collect some witch’s hair—a small pile of hay or some dry, dead grass. You light that, and then add small sticks and bigger sticks before you feed your tree stump into the blaze. Because it’s the small sparks, which start small fires, that eventually build enough heat to burn the whole fucking forest down.”
“We’re either getting better or we’re getting worse.”
“You are giving up instead of getting hard! Tell the truth about the real reasons for your limitations and you will turn that negativity, which is real, into jet fuel. Those odds stacked against you will become a damn runway!”
“There is no more time to waste. Hours and days evaporate like creeks in the desert. That’s why it’s okay to be cruel to yourself as long as you realize you’re doing it to become better.”
