I think once you get to a point where you can communicate in a language, you can go out into a lot more places where that language takes center stage, and so you can iron out any quirks or imperfections. I feel like this type of learning primes you for immersion and so lets the rest of the learning be done on the fly, or in action.

This sounds like it would work great as an exercise that you would do in order to learn a language, I don't think that it would be the greatest method if it was your primary tool for learning a new language. I personally find the most trouble with grammar structures when learning a new language. If I were to try this I feel like I might have a lot of success on that front, but I don't think it should be someones only method.

I find that when I am learning a language, even when I am taught specific rules of structure and so on, I only truly grasp the concept when I repeatedly try and fail to apply it correctly. Ultimately I do think we have our own indiviual ways through which we understand the world, and by learning, but focusing on the remembering and the application of what we've learned we can come to better understandings.

I think this is great, I'm gonna start giving myself a reward whenever I learn a word in a separate language. Just jokes, but reward is a great motivator. When it comes to language learning I think it goes much farther than punishment, I mean, what would that look like? lol

The human mind is a powerful thing when it comes up against a problem it knows it needs to confront. This is why immersion can be a great way to learn. If you put up walls you can only scale with language you're bound to learn.

I'd like to make the point that this myth probably comes from when kids are immersed in a completely different culture, like when an immigrant family moves to the us, and the first to become proficient is the child in school. I do think children have a slight advantage due to their brains being more malleable, but they also have no choice but to learn the language to get by, where as an adult can say, use google translate, or ask for a translator in specific situations.

A fixed mindset will definitely get you no where. By definition being fixed is to be set in position, to not move. In order to learn a language at all you need to be willing to grow. I've learned to acquire more of a growth mindset since it was introduced to me in middleschool.

Could you argue that body language or gesture is a language? A side eye could communicate plenty where a sentence might not be useful. The same sentence with a different expression could mean the literal opposite. Define language as exclusively words then no.
