That´s one of the things I´m working on to become a (better) writer.
One example. I just wrote a story and I started with 2 characters standing
in line for a job interview. Then of the characters saw another character (character 3 already)
and so character 1 told character 2 a story about character 3. In the story there was
another character (4).
I added a narrator (1) and a listener (2) to the story to tell the story of 2 other
characters (3 & 4) and ended up with an overcomplicated structure, 2 locations
which have nothing to do with each other and a story which doesn´t help the
cartoon style comic that I´m drawing.
Solution for me, getting rid of character 1 & 2 and just focus on one location and
2 characters and that made the story easier to understand.
I can´t say anything general about writing or the stories of other people because
I don´t have the knowledge or experience to give advice and stories are individual.
I enjoy watching a series like Lost with many characters, story and backstory,
in Game of thrones it was the opposite for me. When I read comics I prefer limited
characters and locations because it makes it harder to follow and I often wish comic
creators would write / draw stories which are easier to understand because I often
don´t have a clue what´s going in the story because it´s too much information
