Fierce Agency®
Be the Best Leader You've Ever Had
Ivy League-trained lawyer and undefeated MMA fighter Jess Sargus reveals the elite athlete mindset behind self-leadership, fulfillment, and joy.
The number one regret of the dying is that they wish they'd had the courage to live a life true to themselves, not the one others expected of them.
You don't have to have that regret.
You have the power to change your life with Fierce Agency.
When you practice the same mindset principles used by the world's most elite athletes, you'll become the best leader you've ever had.
The power to lead the life you actually want to live is already yours.
You'll learn how to use it. Starting now.
We live inside systems that train us out of our power and creativity, teach us to wait for permission, and confuse success with fulfillment. Endless scrolling leaves us numb and disconnected from who we are and what we truly want. As the world polarizes and rushes to outsource our thinking to AI, we lose our freedom when we stop believing our choices matter.
To reclaim that power, Sargus draws on neuroscience and performance psychology to demonstrate that freedom starts with choosing yourself, failure is just information, and you don't need to be fully ready to shoot your shot.
Across 15 chapters, you’ll learn:
- Why centering yourself in your life is the essential first step to being its author, not just a non-player character.
- Why success doesn’t guarantee fulfillment and how to define it for yourself instead.
- The 3D Method: how being Delusional, Determined, and Detached helps you perform.
- The Five Pillars of Fierce Agency® (Growth Mindset, Action Orientation, Present-Moment Focus, Process Over Outcome, and Mission Alignment) and how to practice each one starting today.
- Five guided journal exercises that help you unlearn limiting beliefs, audit your energy, increase daily joy, and define your bold mission, plus mindset training for high-stakes moments and increased focus.
Along the way, Sargus introduces us to a Marine firefighter building affordable housing for veterans, a single mother turned executive whose retirement shows that smaller can be bigger, and a South Philly fighter who rose to UFC and entertainment stardom. She also opens up about her own path from courtroom to cage to boardroom, and the practices that helped her find freedom, flow, and joy.
Fierce Agency will change how you lead your life. With this power, you will become a better leader for others and help protect what's human in a world that needs it more than ever. This is your green light to be the best leader you’ve ever had.
