If you were given $11 Billion in Gold, on the condition that $6 Billion is reserved to spend on charity, philanthropy, helping people including family, friends, people overseas it's up to you. The remaining $5 Billion is for you to spend on your dream, passion, muse, obsession (whichever word describes that one project or 100 projects or inventions, innovations, films, stories, books, products, services - whatever your purposes are on earth in your lifetime. What are you going to do/create/put in place in the world that will change the course of global events. Whatever you do with it will make it ok when you die. You''ll have no regrets because you had the resources (and you used them) to do what leaves your legacy that affects the world for the rest of time. What is your legacy you'd spend $5 Billion to make happen?

If funding your dreams is easy because you have more money than you could ever spend in a lifetime to make them happen, what would you do. The $5 Billion would be spent on your lifestyle and on building whatever your passion, dream, muse or obsession is... and how would that affect the world now and for future generations? Why does it matter? Here I refer you to the best source for figuring this stuff out:
