Fortunately, the doctor sellotaping my knee back together was very good-looking.
Things don't always go to plan, and on this occasion, I had gone crashing down on a chalk path and smashed my knee open.
I had also torn open a hole in my favourite jeans. But a forgotten gift from a friend came in handy: gold, sparkly star-shaped patches. My jeans are now far more amazing than they were before. (And my knee is fine.)
It's the same with art. Things will go wrong – paintings won't turn out how you wanted them to, stories wind up at a dead-end, or all of your film was over-exposed.
The trick is to not be afraid of mistakes, missteps or wrong turns, because you never know – they could lead to fabulous golden stars.
