Persistence

In this summer vacation, I exercise on my willpower.
I have been reading Japanese, do reviewsion, learning new knowledge one unit a week.
Then, the accumulation of knowledge will be a lot more, but even harder.
A few days ago, I think that the use of adjectives is very boring, now turn to the verb.
I know the verb is the center of the vocabulary.
And Japanese verbs fall into three categories, really difficult to remember.
I began to encounter difficulties, but I believe I could overcome them.
Need willpower.
