Just want to say, thanks for the advice, from you and everyone who commented here.
After a long time in which I almost completely forgot about this post, I started to write in English. And I also finished my first short story after re-writing it for 3-4 times and getting my family to help with the English slang and the construction of phrases. I built my own method of writing which is; to write the first draft as loosely as I can with great focus on the plot, even though some things in the story or some sentences don't add up or don't even make sense, it didn't matter, because I would rewrite it nevertheless. and then I would keep doing that until I have a clear picture of the story and the plot and every loose end would be tied. still, the dialogues are a burden to me.
But my dilemma still goes on, after more than a year of writing in English a voice in my head still tries to convince me to write in Hebrew (my native language). then I composed a pros and cons list of writing in English VS Native language.
Pros of English: Bigger market, easier to get published (I can publish my books on amazon KDP. ), Easier to get fans, readers, and an overall crowd.
And now we move for the Cons of writing in English: my writing is really slow (a max of 500 words a day), and since I have many grammar errors I need an editor for that. Also, I would probably won't immigrate from my country, a thing that would make it harder to maintain the English voice and slang, and the last thing which is the dialogue.
Now, the pros of writing in my Native Language: much easier to write (at least 1000 words a day without breaking a sweat), I would finish books quicker, I would probably would not need a freelance editor since I could only publish with a book publishing company (and they would provide everything.) the dialogues and voices of the characters would be ten times easier. Also, I consider myself a pretty patriotic man, and I kinda believe that if I write and publish in my country it would support the market.
A thing that always jump to me as an argument is Paulo Coelho, he is a famous writer who translated his works to English (you've probably read his most famous one "The Alchemist") and then I say to myself: "if I'm truly good at writing, I could make it in any language."
But when i look at the Cons of Writing in my native language:
I can't publish it on the internet in an Ebook format, the market in my country is pretty small and even the successful writers here, and I mean REALLY successful, that are known, by almost everyone in the country, make just the same as a worker on a minimum wage. its pretty sad.
I think that the real difference is when you start out, I think that it would be easier to start to publish in English in amazon KDP, but I also believe if I'm good I could be translating my work to international audiences.
What do you guys think?
