You need to live in a dome initially, but over time you could terraform Mars to look like Earth and eventually walk around outside without anything on... So it's a fixer-upper of a planet.

I could go and buy one of the islands in theBahamas and turn it into my personal fiefdom, but I am much more interested in trying to build andcreate a new company.

The one that will put the first human colony on another planet is certainly the most important human on Earth. And you can judge the rest of mankind of his time by how they judge him along the way.
