I'd consult a financial planner and also research on my own how to keep the money growing.
I'd make sure my family is provided for.
I'd set up a small off-the-grid block house with a sea view. House would be entirely solar and wind powered with a nice garden and perhaps a couple of guest cottages free to my friends for vacation stays.
I'd buy a beat up white toyota.
Then I'd set up a foundation and entertain grant proposals for Jamaica friendly endeavors that are sustainable and will serve the needs of the people.

Now where did I put that lottery ticket?
