U.K. truck driver, Stephen Chick, 58, just won the Euromillions lottery. He was too busy working, and was unaware of the win until a week after the numbers were announced.

Not only was he so consumed with work that he forgot to check his tickets, but it’s also the reason he picked the winning numbers in the first place. Chick would write down all the numbered license plates of other trucks he saw as he traveled on U.K. highways, and play them in the big game.

He told reporters: ““I picked them off the back of lorries and by the end of the week I had my numbers. I couldn’t believe it though when they actually came up.”

He is now planning a trip around the world with his wife, but doesn’t mention if he will continue driving or not.
