info_outlineKrista Ryan survived the mass shooting at the Route 91 Harvest Music Festival in Las Vegas. Years later, she faced another life-altering challenge when she was diagnosed with stage 3 rectal cancer.
Four surgeries, chemotherapy, an ileostomy, and a difficult recovery followed.
But Krista kept going.
She joins Chuck Carroll to share the resilience philosophy she calls KFG: Know, Focus, Go. The initials also carry another, considerably more forceful meaning that captures the determination required to move forward when life becomes unimaginably difficult.
Krista explains why true resilience does not mean hiding fear or pretending that everything is fine. She shares how allowing herself to feel anger, grief, and vulnerability ultimately gave her more strength.
You will also hear how a brief conversation with another cancer survivor prompted Krista to seek testing, what it was like to tell her children about the diagnosis, how humor helped her through treatment, and why even the smallest action can be a meaningful act of perseverance.
This episode is for anyone living with illness, recovering from trauma, supporting someone they love, or searching for the courage to write the next chapter of their story.
