Learning to write good English is not easy. Even many native English speakers cannot do it.
The best writers in the world have read a lot of books, written a lot of papers that were corrected by qualified language instructors, listened to feedback from readers and worked hard to understand their subject matter well enough to write something worth reading. It takes many years to develop good writing skills, but a little regular effort over the years will pay rewards. Also, be mindful that people who use social media often have poor spelling, use poor grammar, skip punctuation, don't capitalize proper nouns and in general are bad examples for people who want to be good writers.
