In 2017, Mark Watson - a man prone to considerable anxiety, with multiple phobias and a history of piss-poor self-esteem - was asked to go on Celebrity Island with Bear Grylls.

But the experience changed the shambolic comedian for the better, and now he's written a sort of motivational talk about what it taught him. But still with jokes.
