What would you do if/when you become a billionaire?

My Entry :

Well, I wouldn't do much until I make my first couple of Billion dollars apart from fulfilling every single wish my mom has. Once done That's when the madness begins. I'm going to do the following:

Give a hundred crores to someone whom I've promised I would. It's revenge, not generosity.
Adopt several kids and pups, instead of opening orphanages or doing charity. I hate charity.
Buy huge lands in city centres across the country, build a wall around and let them turn into tiny forests.
Burn a billion dollars (my favorite)
Sponsor for the education and all other expenses of families of our martyrs.
Leave the rest with my mom or brothers to decide they'd like to do.
Buy a house in the Himalayas, a wooden house, with a garden. Shift there with my dogs forever. Funny how this one's the best and worst case scenario of my life.
And of course continue to trade till I die.
