I actually really love grammar! It's just that I never put aside the time before, plus I had a hard time figuring out where to start. My approach has had the surprising benefit of giving me a more intuitive understanding of sentence structure; but actually producing sentences myself is very daunting, still.

Since German as a language has a lot of similarities to parts of the Korean grammar (especially with forming tenses, irregular verbs, verb stems+endings as conjugation, plus endings for adjectives etc., objects/subjects being slightly different (though not because of particles but instead via declination)), I generally find that part intriguing but not off-putting.
