How much Chinese did I learn in a year?

During the first few months of learning Chinese, I wanted to turn my learning into an experiment: how much Chinese would I be able to learn in a year? This motivated me greatly, but of course I did not stop after a year. But where was I, a year into studying Chinese in a highly immersed way? I was able to speak quite a lot, more than I initially thought I would, but there were also many aspects of the language that I had only just started exploring and I was making a lot of mistakes. Yet, these mistakes helped me learn more. I would rarely make the same mistake twice! So, a year in, did I think Chinese was difficult to learn?
