100% agree. I've found more success with reading books in foreign languages and my native language when I don't hyperfocus on looking up or understanding every word. I expanded my reading comprehension and ability very quickly as a child by letting myself figure things out with context clues and not understanding 100% of what I read.

It can also be good for the brain to have to work at understanding - the crutch of looking something up immediately can make it easier to forget what you've already looked up, compared to struggling with something and turning it over, which can make it easier to recognize, remember, or elaborate on your contextual understanding the next time you encounter it.

(This is an aspect of effective studying - making your brain work to recreate and recall something, like in working to remember the subject of a lecture, is more effective than just giving your brain the answer, like in re-reading notes.)
