When I'm rich, I'm going to build a self-sustaining space station and live life orbiting around Earth, doing business on the internet through from my space station. I'll hire people to work there, cooking my food, doing work in the oxygen producing garden (also getting me food), tending to the livestock, making sure we don't hit any space junk, etc. I'll get shipments of stuff (with outrageous shipping prices which I won't care about). I'll have a giant main room with comfy space-age furniture and a giant screen on which to play games or conduct video calls. It'll be sweet. Then at some point I'll colonize Mars, of course.
