Mine would be living a good life with no cares other than my family's needs not having to worry about money ever again. I'd probably want several beautiful women included that would live an immortal life none of us ever aging beyond our twenties, and living on a beautiful island with white sand beaches, palm trees, and water so clear you could see all the beauty of the sea creatures swimming around the vibrant colored corral reefs. I wanted to be an oceanographer but ended up an over taxed peon slave to the government.
Lol I never seen white sand outside my daughters sandbox and on tv, and yes I have seen black but again not actually got to walk a beach of it and no I never knew there was pink sand.
