I guess it's the same thing I'd do if I won the lottery.
Quit my current job.
Find meaningful work that would contribute in some positive way to the world.
Travel extensively: South Pacific, Europe, a number of islands, Australia, a number of places right here in the US.
I would work out more and do more yoga
Write a book or two
Move to a place that has more scenic beauty but not isolated
and read some more
Make a documentary about the JWs ala Ken Burn's "Civil War" style.
