I think most people can learn a lot more than they think they can. They sell themselves short without trying. One bit of advice: it is important to view knowledge as sort of a semantic tree -- make sure you understand the fundamental principles, ie the trunk and big branches, before you get into the leaves/details or there is nothing for them to hang on to.

Q: Spacesuits. How does SpaceX plan to address the limitations and contribute to the advancement of current spacesuit technology to best serve humans enroute and on the surface of Mars? You mentioned in 2013 that there'd be an update to SpaceX's "spacesuit project" soon - how is it coming along?
A. Our spacesuit design is finally coming together and will also be unveiled later this year. We are putting a lot of effort into design aesthetics, not just utility. It needs to both look like a 21st century spacesuit and work well. Really difficult to achieve both.
