We all know about certain problems we wish we didn't have.

I remember, as a kid, thinking more about, you know, watching the world go by and being amazed by how both complex but consistent and elegant it was. You know, why, you know, when you put that cold glass of water on the table, it kind of warms up at a very predictable way.

I started realizing that I wasn't so dumb; rather, most people simply didn't know the answers to the questions that I was interested in-or they didn't care.

I've never regretted anything I've done, even the things that I've failed at. I've often regretted not trying something really big, because you'll never know.

As a kid, I was less interested in the physical tinkering than thinking about what we would now call the physics, as opposed to the engineering.

In some cases, inventions prohibit innovation because we're so caught up in playing with the technology, we forget about the fact that it was supposed to be important.
