Winning The Upper Hand means to gain an advantage or control over a person or situation. The purpose of this book is not to put you in a winning position over another person. (Plot twist.) It's to give you The Upper Hand over yourself.
This book gives you the tools you need to deal with the adversities you currently face and those you haven't faced yet. It all comes down to changing your mindset so you can consistently "win the moment in the moment." This book has the power to change your life. Spoiler: Things are about to get uncomfortable.
