What would u do if u win a lottery

Honestly I would pay off my mums mortgage, buy a house here and one in Brighton for my gf to live in as heck I can always sell it afterwards. Then I would pay off her parents mortgage and that of one of my mates (well they are twins) cos I have known them for years and know their mum would appreciate it. Other than that I would have not much different to how I have it now just a little better and run businesses with the hope that one would work/keep me occupied.
