What are the key words for first person pov?I decided to brush up on old essays from the past and learn a little more about writing. and i realized...

First person point of view, as you say, is when a narrator tells his or her story using the personal pronouns I, me, my, we, our, ours, etc.  Second person point of view refers to how we might directly address a person, for example in conversation, when referring to someone or something as "you" or "yours."  Third person point of view is when a narrator tells his or her story from outside the story, an independent observer, using the pronouns he, she, it, his, hers, its, etc.  Within the third person point of view are defined the third person limited narrator, who knows and expresses the inner thoughts and feelings of one character, and the third person omniscient, or all-knowing, narrator, who knows and expresses the inner thoughts and feelings of all characters in the story.
