Question

How is the first person narrator limited in a story ​

Answer 1

When a story is in first person you only know the characters thought it’s very limited vs if it was in third person you would know everybody’s thoughts

Answer 2

As you are writing entirely from one person's point of view, first-person can be very limiting. The reader can only experience the world through that character's eyes, and so as a writer you cannot share the thoughts and feelings of others, only your narrator's interpretation of them.
