What would I do if I won the lottery?

If someday I won the lottery ... I have so many option about things to do whit that money going around my head.
The first thing I would like to do, is to continue studying, because having the possibility of studying without having to work at the same time for example is a unique option in life. Secondly, I would like to travel around the world with my family, we love to do that and we try to get out Santiago to have a change of air and do different things as a family for one or two weeks. With that amount of money, that one or two weeks would be al least a month.
The things that I would do next, would be to buy houses, one for me and another to my parents, both with a big garden, so my mother can have the garden with which she has always dreamed, where she can plant different spices, fruits and vegetables, and my father can have a warehouse large enough to have all his things, and he can work fixing things during his free time without bothering with noises or smells to my mom. I want a house with a big garden to rescue pets from the streets, to give them a home with love and anything they needs.
In the same line, I would like to make a big donation to an local ONG that its cause makes me fall in love, like protect the nature or save children or animals from bad situations.
And in orden to keep having money to the the thing that I like, I would by one or two flats, to rent them and make money with it.
 I think that everyone dreams with having a lot of money.
