"Practice."This saying is appropriate for every profession. Those who sit back and do nothing will never soar to the top as their stones remain in place forever.
However, the harder we try, to an extent this will yield fruit. The man who drives himself so hard that he can still find the reserves of strength needed to overcome his opponent, will come out on top in any sporting event."
I suggest trying different styles and genres, and this will help you sharpen your abilities. It helps to read different types of books which is certainly a good way of developing voc-abulary and a sense for language rhythm. As well as possible seek feedback from others; if the criticism is constructive, it can point to ways of improvement. Stay consistent, make writing a fixed habit.
