$100k?
If i wanted to make money i'd open a Multi-Gaming Centre in Jurong
Point. ie. Lan-Gaming, X-box Gaming, PS Gaming. Did a survey before
and there are tons of kids who want something like that here.
Otherwise, i think i'd go backpacking with that money around the
world. Minimise expenditure and see if i can put my money to any
good use, esp in the 3rd world countries while seeing more of the
world.
