How to Write in First Person?

To write in the first person, one must refer to themselves with such terms as ‘I’, ‘ my’, etc., as if the person telling the story is writing about themselves. This is opposed to the third person where one would refer to themselves by their name. For example, ‘I went to the bank the other day’ is written in the first person, whereas ‘Janet went to the bank the other day’ is written in the third person.
