Thanks to God, I have mastered reading, but now I do not know writing

All thanks to Allah (or Thank God), I have mastered reading, but now I need to learn how to write (or but I do not know how to write)

The more you practice writing, the better you'll become. Your writing isn't bad at all though. Keep up the good efforts!

What are the steps that make me write well??

I find that making a habit out of writing each day, even if just 4-5 lines will definitely enhance your ability to both write and articulate your thoughts onto paper. As long as you get good feedback and you analyze that feedback, then your way to good writing is guaranteed, inshalla.
