In the first 7 months of this year (6 months if except the Jan), I input about 1600 items, and in the coming next 5 months, I have to  input about 8000 items. That is, I have to input about 8000/150 (~ 50) items everyday.

50 notes everyday! And I must publish 2000/150 (~14) items everyday. Well, I must make great efforts to reach it.
