At 10:22 this morning I finished RTK1! I started on March 14th, so I think that makes about 3 and a half months. Here is some random information:
Among my most missed kanji were: 暫 temporarily, 刺 thorn, 別 separate, 貯 savings, 場 location, 議 deliberation, 失 lose, 浸 immersed and 誇 boast. Of course this list doesn't have many of the later kanji since I haven't had time to review them many times, much less miss them many times.
The hardest chapter for me was the "heart" chapter, especially kanjis with the "state of mind" primitive. The "finger" chapter and the late "tiger/deer" chapter felt especially easy for me.
Other primitives that gave me trouble were some of the later plant/vegetable ones (salad, celery, cabbage, bush, corn, etc). "Taskmaster" gave me a lot of trouble until I changed it to "ogre" about halfway. Then it became one of my stronger ones.
My most starred stories to date are 観 outlook (8 stars), 笛 flute (5 stars) and 錯 confused (4 stars). Please check them out and give me more stars.
That's it. Anyway, please congratulate me.
