Paul McKenna, PhD., is a British hypnotherapist, behavioural scientist, broadcaster and international best-selling author, who has been described as one of "the world's most important modern self-help gurus".

On Saturday, February 23rd, McKenna brings his live show The 3 Things That Will Change Your Destiny Today! to the RDS, Dublin.

Speaking on Dermot and Dave, the Londoner tells us how, "It's not a lecture. It's very much an interactive experience. It's like a mass hypnosis session". He claims his teachings can change a person's life in 7 days by getting them to focus on their priorities. After all, "purpose is the cornerstone of good mental health".

The 55-year-old also reveals some advice he was given by Simon Cowell and praises the benefits of 'HeartMath', which can change your frame of mind in just 60 seconds.
