How to start writing ?

The worst thing that can happen to you as someone who aspires to be a writer someday is to stop writing and forget your idea completely. Some of us stop writing for long periods of time, for different reasons.
There is a misconception that only way to write a book or a novel or even a post is to start writing once from one to the other once considering that the writer sits to write the first chapter and then the second chapter in the same order you read it .. if the writer did not find the appropriate beginning is waiting or looking or perhaps forget the whole idea and preoccupied with things and may not return to it again .. this is worst scenario that can happen .. is a method followed by some writers, but not the only…
The most common method is the method of drafts or manuscripts Mancript is to initially write your idea as primitive as I thought to write directly on paper .. And then begin to build and vaccinate with new ideas .. It is okay to be bad writing at the beginning .. with time rewritten and develop some up to rewrite his book or his story over ten times to reach the level of satisfaction .. And some remain years in writing and rewriting ..
You can also start the idea of a novel in the form of a short story .. or the idea of a book in the form of an article .. then follow the same style in writing and rewriting up to the best level you see..
In any case, the common denominator of all these ideas is to write or start writing your idea. Just your dream of writing and thinking about the idea of your writing remains as they are just unfinished, unrealistic ideas on the ground and writing a bad script as much better start than the death of your idea that you dream of writing..
