I find it hard to believe you wrote day in day out 10 posts per day with at least 500 words, and they all were good. This means 5000 words per day, a novel in a month. If that's the case, how come after all that practice you find it hard to write about something?
Why did you leave if they paid that well? I wonder if you are willing to pay to read for the content posted here?

P.s. It would also be good if, when you mention someone, write the name without spelling mistakes.
