Elon Musk is one of my role models when it comes to thinking big and combining business with vision. This article talks about where his company SpaceX is going and explains a bit about Elon's philosophy and vision:

“I was trying to understand why rockets were so expensive. Obviously the lowest cost you can make anything for is the spot value of the material constituents. And that’s if you had a magic wand and could rearrange the atoms. So there’s just a question of how efficient you can be about getting the atoms from raw material state to rocket shape.” That year, enlisting a handful of veteran space engineers, Musk formed Space Exploration Technologies, or SpaceX, with two staggeringly ambitious goals: To make spaceflight routine and affordable, and to make humans a multi-planet species.

Musk makes no secret of the end goal: Create a new civilization on Mars. Speaking at the National Press Club in Washington, D.C., in September, he outlined the business plan -- if that’s the right term for something that looks decades into the future. “If you can reduce the cost of moving to Mars to around the cost of a middle class home in California—maybe to around half a million dollars—then I think enough people would buy a ticket and move to Mars,” he said. “You obviously have to have quite an appetite for risk and adventure. But there are seven billion people on Earth now, and there’ll be probably eight billion by the midpoint of the century. So even if one in a million people decided to do that, that’s still eight thousand people. And I think probably more than one in a million people will decide to do that.”
