JLS star Marvin Humes has revealed he's an avid reader of self-help books and puts his success down to them.
He said: "These books teach you to have a positive mental attitude. I started reading them when I was working nine-to-five and carried it through into the band."
With 4 chart topping singles, a number one album and a gorgeous girlfriend (Rochelle from The Saturdays) it seems to be working.
