Creating Manga or Doujin

Young/new storyteller and illustrator here.

Any Mangaka or Doujinshi around? Even an amateur is fine.

I would like to hear some people's stories about making their dreams a reality, and maybe some tips or advice they wish to give amateurs, whether it be about storytelling aspects, drawing or illustrating aspects, or the process of combining the story and artwork.

Bear in mind, that I am brand new, so please don't hesitate to tell me of something that is even obvious.

anything they feel like sharing would be great.

Thanks.
