Your probability of dying on Mars is much higher than earth. Really, the ad for going to Mars would be like Shackleton's ad for going to the Antarctic: "It's gonna be hard. There's a good chance of death, going in a little can through deep space. You might land successfully. Once you land successfully, you'll be working nonstop to build the base."

What I'm trying to do is, is to make a significant difference in space flight. And help make space flight accessible to almost anyone.

The space shuttle was often used as an example of why you shouldn't even attempt to make something reusable. But one failed experiment does not invalidate the greater goal. If that was the case, we'd never have had the light bulb.

If humanity doesn't land on Mars in my lifetime, I would be very disappointed.

In order for us to have a future that's exciting and inspiring, it has to be one where we're a space-bearing civilization.

If you look at our current technology level, something strange has to happen to civilisations, and I mean strange in a bad way. And it could be that there are a whole lot of dead, one-planet civilisations.
