The Journey of Becoming 2.0
I started reading because I wanted to build a company. What I didn't realize was that every book, podcast, and biography was quietly rebuilding me.
They weren't just teaching me how to build a business. They were changing the way I thought. Every story, idea, and lesson challenged my assumptions and gave me a new lens to see the world.
That's when I realized the value wasn't in consuming more knowledge. It was in becoming someone different because of it.
The problem was that every insight lived in a different place, and turning those insights into decisions was still my responsibility.
So I built a companion I wished I had: a place where the ideas I discover can be explored, challenged, and turned into actions that shape who I become.
That's why Open Citadel exists.
