Introducing our keynote speaker…

The Obstacle is the Way
Speaker: Ryan Holiday, Best-Selling Author & Philosopher
As one of the world’s best-selling living philosophers, Ryan Holiday delves into the wisdom of history’s greatest figures and how they used obstacles as the stepping stones to success. From ancient philosophers to modern-day business leaders, he shares examples of how embracing the challenges that stand in our way can help us achieve our goals. He’ll show how to turn setbacks into opportunities, how to use adversity to your advantage, and how to find hidden opportunities in every obstacle. By the end of this talk, CEOs will have a new perspective on the challenges they face and be equipped with practical strategies to overcome them, using adversity as a strategic advantage in today's competitive landscape. It’s time to stop seeing obstacles as roadblocks and start seeing them as the path to success.
About Your Keynote Speaker
Since best-selling author Ryan Holiday introduced Stoicism to the world with The Obstacle Is the Way, this simple but powerful philosophy for life has taken the world by storm. This brilliant and engaging book is an invaluable source of wisdom for anyone who wants to become more successful at what they do. The New England Patriots and the Seattle Seahawks invited Ryan to visit their headquarters to talk about the ideas in the book. NBA all-star Chris Bosh listed the book as an item “he couldn’t live without.” In addition, other books like Ego Is the Enemy, The Daily Stoic, and the #1 New York Times bestseller Stillness Is the Key appear in more than 40 languages and have sold more than 5 million copies. Together, they've spent over 300 weeks on the bestseller lists. Ryan lives outside Austin with his wife and two boys...and a small herd of cows and donkeys and goats. His bookstore, The Painted Porch, sits on historic Main St in Bastrop, Texas.
