• Brandon Block is a British club DJ. He has appeared on reality shows like Celebrity Come Dine with Me and Celebrity Big Brother. He's also had a high-profile battle with addiction, and now launched his own wellness project to bring self development to the masses. It's called Happy Days.

After his addiction issues, he trained to help others affected by drugs and alcohol. That training helped him to form his own ideas around his new self development project. Part of Happy Days is about mapping your dreams, and setting your goals in an effective way. Who would have thought it? Celebrity hellraiser Brandon Block is now on the straight and narrow, and he's an absolutely lovely chap as well.

He starts by talking about just how bad things had got, when he was at his substance-abusing worst.
