If I would win the money I probably would keep 20-50 million for myself and the rest I would use for investments in projects/people.

in my city Brussels:

- Buy some industry terrain/office buildings that are empty for years and transform them in parks (love hanging out in parks) with some soccer/basketball etc terrains on it if possible;.
- More security camera's..
- Build camps where people who live on the street can go to for a bed and food and help..etc
- Create work for unemployed, as an example train unemployed in making furniture that will bump up their wellfare a little and at the same time the stuff they create will be given to people who can't afford to buy furniture themself.
- More hobby places (Skateparks, sporthalls, graffiti walls, etc..)
-Build biggest Chinese gate in europe (in your face Antwerp/London and Den Haag =p)..
- Build Tibetan temple/museum/restaurant etc..
-Invest in science (Cures for sicknesses)
- Give some extra money to the orphanges in chengdu and Thailand that I already invested in...
- More public toilets...
- Invest in Green Energy (the created energy can be used for free for the families with the lowest income(s)).
- More city cleaners..
- (More) Free internet hotspots.
- More investments to give some neighbourhoods an more friendly and cleaner look
- More free festivals/parties...(Dance/Worldmusic/Halloween/X-mas etc;.)..
- And a lot more stuff

Summary: Trying to make the city I live in for all its inhabitants and at the same time it will also make my life better :).

Wait... are you naked ?
