As an advice, I don't really have to say a lot but,
Start writing! At times you may feel like it's not your cup of tea, you may feel like you can't do it, but just start.
You can't know whether you know or don't unless you try it out.
I personally didn't know whether i can do it or not until I tried it out. And here I am, right now, already published 40 chapters of my book and still gaining experience.
I am not perfect, not yet. I just started writing and as I continue, I am gaining more experience.
Since we are here to make Friends as we gain experience, don't hesitate to pm me for any advice and help. I would love to help you and become friends.
