Well if this is totally divorced from reality, then...
1. Next to the indoor beach of a self-efficient space colony orbiting Earth, so If I look out one window I see a beach and out another I see space.
2.Married to the perfect woman or at least my concept of her.
3.Well since I went with a space colony it would be a home with everything that I would need, a technologically advanced, ergonomic to all my possible needs and wants as a person. Complete with a personal theater, a computer that I can speak to that controls the various functions within the house.
4.I would live like Leonardo Da Vinci, attempting to discover anything that is still a mystery in that time and getting paid for any discoveries I find...
5.figuring out a system to govern all mankind that would bring peace...I know that sounds like a Miss America answer but that would make my name be remembered for as long as their is peace...
