If I would win 1,700,000 pounds, the first think I would probably do would be depositing a good part of all the money in a savings account that I might need later on. After that, I would invest £100,000 in my own startup company such as a modern-looking library like Cărturești where everyone, from adults to their children, could borrow or study their favorite books. I'd also try to import foreign books so people could start learning new languages! Also, I would purchase a nice vehicle and a house when I'll turn eighteen years old, but not very expensive ones because money come and go like a feather in the wind.
