One of my big problems as a Japanese language learner is that I’m afraid of making mistakes.

Of course, I know everyone says don’t be afraid of making mistakes. Your grammar doesn’t have to be perfect, you just need to communicate.

So nothing demotivates me and pisses me off more than when you get a response of “wtf” to a small error, as if you were speaking in tongues.

Like, actually, your Japanese does have to be perfect, sorry.
