Did you have experience with designing products before? If not, how did you go about prototyping? Can you talk a little about that process?

Sorry to tell you, but that was a public vote and Pluto is still considered a dwarf planet. :/

This was, in a way, answered elsewhere. Count calories for a few days to track whether or not you're getting enough. (Otherwise you're running blind and it's too difficult to answer.) If you're not, then eat more throughout the day.

I'm not Matt, but I feel you. Before I started ~8 months ago I was running ~13 minute miles. I just ran my fastest 5k at 25:49 a couple weeks ago (under 9 minute miles!). For the first 4 or 5 months I didn't see how I'd ever break 10 minutes a mile for any extended period of time. But with consistent training it happened. I ran a half marathon, slowly, in 2:16:01 and then 2 weeks later ran that "fast" 5k.

Biggest thing: patience. Keep training. Slowly increase mileage. And slowly increase speed when you're comfortable with your mileage.

When I was a youngster I liked to build model cars and planes. The SR-71 was a favorite.

Unrelated, but kind of related: Do you think commercial airlines will ever break the sound barrier again? As an adult now, I'd pay for that experience.
