★Authored by Tim Castle, the Top 30 Negotiation Professionals in the World. In this book, he’ll give you many suggestions for improving decision-making.
★Different from theoretical business management books, this book is based on the author's real experience of surviving on a cliff, transforming the decision-making wisdom in extreme environments into a methodology that can be used in daily life.

Making good decisions quickly is what marks out truly great leaders from the rest of us. Decision-making is one of the most sought-after skills today, but most of us have never been taught, but one most of us have never been taught

Aged 19, I went off-piste snowboarding, way before I had the skills or experience to do so, and very quickly found myself hurtling towards the edge of a cliff face on sheet ice. Within minutes, I was literally hanging onto a boulder for dear life, with my legs dangling over the precipice.

Every single decision I made over the next few hours was life or death. There were no easy choices. Each right decision could be undone by a wrong one, and I was very aware of how close I was to death the whole time: the cold, the wind, the fading light, the fact no one knew where I was, the fact I had no food or water on me.

That day, my brain worked overtime to keep me alive. What I learned has actually been a enabled me to approach decisions in all areas of my life with ease

In addition to sharing my story with you, I will also explore 6 of the best decision-making models, as well as teach you how to maintain the mindset of a master decision-maker. After reading this book, you’ll find making good decisions quick and easy and will no longer waste time stressing over them or avoid stepping up to make them.
