@SaharSolaimani Hey there! Just dropping by and decided sure why not help. First, the way to start sharing your stories is by sharing. Yes! Putting it out there. That's the first step. Sure you would need to learn about story writing also but start with sharing your work. There's no perfect work that exists. It's only perfect when it's in our heads but once we release it out to the world, we have different people looking at it from different perspectives.
So get your story out there! And read more. Not all readers are writers but all writers are readers. To write, one has to know how to read.
I hope this is helpful :)
