Part 1: From Survival to Strength

I wasn’t born into an easy life. Grew up Amish and Mennonite, learning the value of hard work. I also felt the sting of isolation and being different. When kids were hanging out. I was waking up at 4:30 AM to work in sawmills and logging crews.

Life was about survival, not growth.

Even in those years, I found sparks of hope. I borrowed martial arts books, studied every move I could, and dreamed of becoming strong enough to create my own path. The dream grew.
