The 83-year-old's long career is now the subject of a major retrospective opening this weekend at the Royal Academy.

But he told Sky News: "I've had terrible things said about all the work that now people think is wonderful… If you can't survive criticism… you're in the wrong game."

The Royal Academy retrospective brings together his life's work in one show, including his early experimental sculpture, his landmark conceptual work and a new immersive digital work.

While much of Sir Michael's painting has been dominated with depictions of modern icons, like laptops and iPhones, he says technology has made it "harder for people to look" at his work.

"We've become probably the most visual age there's ever been and at the same time it's become harder and harder for people to actually look," he said.

"[Paintings] don't move - you have to come to them, you have to give them a little time," he explained, adding that nowadays people are more "used to something that's doing something for them".

The subject matter of much of Craig-Martin's large-scale, vivid colour paintings of everyday objects - from trainers to paperclips, glasses to coffee cups - is universally understood and easily accessible.

"What's ordinary is what unites everybody," he explains.

"When you buy a coffee, they give you the cup. You don't buy the cup, it's free with the coffee, and yet to make a painting out of it is to give it a certain kind of presence, a certain kind of dignity, a way of looking at it that may be different, to what its value or use is."

Now in his 80s, Sir Michael's work has become sought-after around the world. Not only has he proven to be one of the most successful artists of his generation, he's also been one of the most influential teachers.

In the late 80s, his students at Goldsmiths would go on to be the headline-making Young British Artists, or YBAs as they became known - and they include Damien Hirst and Sarah Lucas.

"They were very, very young," Sir Michael explained. "There were people who said to me that it was very dangerous for them to be having this kind of success because they were so young and my advice to them at the time was 'if the door opens, it's best to go through it'."

Decades before, in 1974, he'd made headlines of his own with a piece called An Oak Tree - now widely considered a landmark moment in the history of conceptual art.

Recreated for the retrospective, provocatively you won't find any big logs propped up in a gallery as the piece is just a glass of water on a glass shelf.

"People often do say to me… it changed my idea about what I thought art was, what it could be, my relationship, and that's an amazing thing to be able to say."

Challenging us all to look with fresh eyes at the 'ordinary' all around us, Michael Craig-Martin's body of work is proof of why he is one of the most extraordinary artists working today.

Michael Craig-Martin is at the Royal Academy in London from 21 September to 10 December.
