I do not know how one can begin writing if one does not read; reading is essential. You could begin with newspapers, magazines, essays, short stories, fiction, non-fiction or even articles. Basically, just aboout everything. The idea is to find a path to the written word. This kind of reading could help you to understand the different types of writing and eventually develop your own style.
Remember to write for a little while, every day.
If you read a lot, then you could begin writing. It does not have to be much, just a paragraph a day. If you keep writing paragraph after paragraph, then you probably could write an essay or a short story. It could become a habit and soon, you could be doing, it not for sake of writing but because you just love to write.
It would help you to find any mistakes, or check if anything is repetitive or just too long. For example, I found that I wrote ‘misakes’ instead of ‘mistakes’. Missing letters are easily found.
Note that whatever you want to say is going through to the other person. It should say what you need to say, not just whatever you want to say.
It will make it easier for you to know if what you are saying is understood by the other person.
If you do it every day, perhaps you could become a writer too. :)
