MY UNTOLD STORY FEATURED IN WINSPIRE MAGAZINE: A JOURNEY OF BREAKING LIMITS AND UNLOCKING POTENTIAL
As a woman, I’ve come to realize that our greatest breakthroughs often come from the moments we dare to be uncomfortable. Sharing my untold story in Winspire Magazine is more than an achievement—it’s a reflection of every challenge I embraced, every fear I faced, and every limit I refused to accept. Each step outside my comfort zone has brought me closer to my purpose, unlocking potential, resilience, and possibilities I once thought were beyond reach. My hope is that by sharing this journey, other women feel empowered to rise, rewrite their narratives, and break through the barriers holding them back. Because when we choose growth over fear, we become unstoppable.

"We all need to stand for what is important for us, for our passion, and if we are in our authentic self, everything will flow at the right time."
- Interview for Forbes Superwoman Sumit 2022
I am so proud and happy to present my bestselling book, Out of Comfort Zone - Raus aus der Komfortzone - Limitlerin Ötesinde. Now available in three languages. My swim and life journey, practical hints for meditation, swimming and mental endurance, psychological reflections, and much more...
A journey about life, about out of the comfort zone and how we break our limits and grow physically and mentally.
There are no limits to what you can accomplish. Except the limits you place on your own thinking.
