Are you learning Korean and Chinese at the same time? Thats sound really cool, but also pretty hard lol. Besides Japanese, I would love to be able to speak Korean one day, but the thought of learning 2 Asian languages at once sounds difficult. I also really agree that you can't be afraid to make mistakes. When I studied abroad in Japan, as a perfectionist, I would often shy away from speaking to natives because of the fear of making a fool of myself (even though I still managed to do that a few times lol). Once of my goals going forward will definitely be to put myself out there more often.
