This document discusses different points of view (POVs) that can be used in writing:
1) First person POV uses pronouns like "I", "me", "my" and tells the story from the perspective of a main character. Benefits include seeing events through an important character, but the narrator may be unreliable.
2) Second person POV uses "you", presenting commands or speaking to oneself. It is rare and uses "you".
3) Third person POV can be omniscient, where the narrator knows everything, limited omniscient where the narrator can see into one character's mind, or objective where the narrator only describes without entering characters
