Found in this fun Hey, Poindexter! interview, which also includes the following inspirational passage:
Why do science? You do it because you like it, because its neat, and you want to make discoveries about the world, the body, about the universe. These other societies see science as a path to something, and it’s a tough path, and yet they’re willing to put aside their personal comfort because they need to.
For the people who get great science education—in the end, it’s all about motivation. You could be motivated positively or negatively, but in the end, if you follow that motivation and work really hard, you will succeed. In this country, it seems like we all need positive motivation to do science.
