Simple question: Would you rather have things or do things? Would you rather travel the world or own a multi-million dollar apartment overlooking Central Park? Would you rather fly to space or have own a Ferrari? All these questions boil down to whether you would own things or do things.
Personally, I'd rather have things. While it is nice to have memories and experiences, those are all in the past-tence. They already happened and are no longer happening. Things, on the contrary, you own indefinitely. It would be nice to travel the world or leave the planet, but I'd much rather own the nicest apartment in New York and drive a 7-figure car.
