First review of Korean improved after the first few days... took awhile to get my mind in gear. Today I started on a Cantonese review, and this came easier... might be because of the smaller gap between first and second sessions, might be because the sentence order and inflections are easier than in Korean.
Code-switching is always fun... working in one language for awhile and then trying to switch, the two merge together for a bit. (Not really code-switching, but close.) I like learning slowly across a range of languages, as frustrating as it can be.
Plan is to continue Cantonese review, then move back to Korean on the plane over. When I come back I may take a week or two with no priorities, get reoriented.
