I meant to update this blog all along, but there seems to be some reason that keeps me from doing it. And today, I have stumbled upon the reason I think that explains the situation fairly well.
Vigorous writing is concise. A sentence should contain no unnecessary
words, a paragraph no unnecessary sentences, for the same reason that a
drawing should have no unnecessary lines and a machine no unnecessary
parts. This requires not that the writer make all sentences short or avoid
all detail and treat subjects only in outline, but that every word tell.
From “The Elements of Style” by William Strunk Jr
And it simply takes huge amount of time to train myself in writing in a vigorous manner.
