Here’s something that would be a bit easier.
It’s not exactly a castle, but it does look modern and comfortable.
However… that’s probably not enough. I could get a few friends to live with me and rent this place out. It would be nice. But so what? I can live in a nice place anywhere in the world. This place is nice but also ordinary. It’s big enough or cool enough to attract the energy I need; people have got to be really excited about this idea for it to take off.
