The 37 year old got his big break in 2005 when he landed the role of Ted Mosby on the hit U.S. sitcom, and has branched out from the show as a director with his acclaimed Happythankyoumoreplease in 2010.
Now he is set to put his life down on paper, and hopes his tome will be eye-opening for fans.
A statement from Amazon.com, the book's publishers, reads, "The story of one man’s unlikely spiritual awakening - this is Eat, Pray, Love for those who would rather be reading (publishing house) McSweeney’s. Josh Radnor grew up in Ohio. He was driven to school in a big yellow bus. He watched The Cosby Show and John Hughes movies. He also went on to become a successful actor in Hollywood. How then, in 2007, did he end up drinking an indigenous plant medicine called ayahuasca with a shaman in Brazil?"
The book will be released in April (12).
