Richard Feynman won the Nobel Prize in quantum mechanics. He was able to learn faster about what the right problems were and how to solve them quickly. The most powerful phrase I've learned as I've been starting to learn languages is how to say, how do you say X in this new language? For example, komonditon, hope, en la français. How do you say hope in French? Whatever the word is, hope, or restaurant, or food, or anything. To me there is something profound about that particular question. But you can go further than learning the word in that language.
