Put half of it in a no-risk time deposit, making sure to ask for a good rate, like say 20% net for 6 months. Put the other half into an investment portfolio, professionally managed of course. Leave both to gain the appropriate interest over a period of 12 months.
Then I'd live off the interest earnings the rest of my life, maybe with a simple house somewhere in Subic or Lipa, anyplace near the sea, s'long as there ain't much pollution and congestion. Get a nice mid-size SUV like a Land Rover Discovery for my transport needs. Remodel and renovate the old family home for my mother who refuses to live anywhere else.
Support the Tulong Dunong program of the High School and Mother Theresa's two halfway houses with half whatever interest earnings I make.
Start a few small businesses like my own small chain of money changers, computer rental shops and seedy videoke joints (you'd be AMAZED how easy it is to make these things succeed). Once these make good, set up my own publication, like a local Atlantic Monthly or New Yorker or Harper's Bazaar.
Put out contracts on all my enemies.
Oh, and retain the services of the Law Offices of Giant, Ghostrider, Maverick and Cackler.
