I would spend some of the money on a good trip for my parents. What's more, I would also go on a special trip around the world, I don't mind going with or without company. With the rest of the money I would do two things: I would keep one half in a bank account, in case I need the money in the future and I would give the other half to someone who needs it more than me.
I wouldn't probably change my way of life, I would still live in my house and go to my school. A million euros doesn't last forever.
