It is very interesting to know that my writing ability has degraded so fast. I don't even realize that it has been so poor like this. It took me only a mere 10-minute duration to write a short paragraph a few months ago while I was practicing my vocabulary everyday, but now it takes me more than half an hour just to produce a short passage. I questioned myself too whether it is because the subject that I am writing now is much more difficult than the subjects I wrote before. The answer is not much. The point is my stock of vocabulary has decreased as I haven't practiced much lately. Anyway, that's a wake-up call for me. I should restart my vocabulary learning.
