John Brennan , well known to many people in recent years as one half of "The Brennan Brothers" in the "At Your Service" , has written a book titled "My Name is Jhon".
The title is just part of the story of John's life and he talks about being diagnosed with dyslexia at an early age, and how that led to him being very often at the bottom of the class.
Speaking on the Joe Finnegan Show today though, John says his determination not to be defined by his condition created an ambition that was matched only by his business acumen.
He says he hopes the book will give hope to parents and motivation to teenagers to "think outside the box" and not allow themselves to be labelled by an educational system.
