Imagine you’re learning a new language, and you find a word you don’t know. If you look it up, you’ll understand it the next time you see it. But if you don’t look it up, you’ll never know what it means, and the gap in your knowledge will stay there. If you keep ignoring these gaps, you won’t get better at the language. This idea works for everything we learn. If we don’t try to fill in what we don’t know, we stay confused. To improve and make better choices, we need to find out and fix what we don’t know.
