What Happens When You Get Better?

You learn like 90%, 80, 90% of the whole language in your first year. And then the second year, you go from like, 99.1 to 99.2 to 99.3. The improvements get so marginal that it does become really hard to tell if I'm actually improving. There's certain things that you can point to, but a lot of like, for me that improving my pitch accent made a huge difference.
