Picture the scene.
Pablo Picasso is in his Paris studio labouring over another cubist masterpiece.
He’s joined by a friend who’s interested to see what he’s doing.
The friend takes a look at the picture, but the way he sees it, there’s something wrong.
For a start, the woman in the painting has both her eyes on the same side of her face.
So he picks up a brush and tries to correct his friend’s mistake.
The moment his brush touches the canvas, the picture stops being a Picasso.
Everyone’s entitled to their opinion, and anyone who feels the creative urge should pick up a brush and start painting.
But not if it means painting over someone else’s work.
There are plenty of empty canvases out there in the world.
So if you want to do things your way, go find one of those canvases and paint your own.
It might even be a masterpiece.
