One of the most important things we have to decide when writing is the point-of-view (POV). The most important thing to consider when deciding the POV is deciding your main character and if secondary characters also want to show their point-of-view. This is especially true in romance, many of the stories are written from the viewpoint of the two main love interests usually in third person. Although I have read a few that are in the first person. Just remember to stay consistent throughout the book. (But even then there are exceptions to the rule such as American Psycho by Brett Easton Ellis, which starts in first person and ends in third).
First person POV is limited to what the main character can see and feel. This is especially great for emotional connection to a character and individual character growth. The third person POV can be more flexible and doesn't depend on staying on one character throughout the entire book. For third person try to keep a limit on the number of POVs in one scene because the reader can become confused on who is thinking and doing what in the scene if the POV keeps changing too much.
The character's POV also has to do with your character’s reveal. The POV can explain characters personality traits such as confidence levels and what is important. Do you want the reader to know everything up front or do you want your reader to slowly learn about your character in phases as the story progresses? I have mixed feelings on this. Honestly, it has to do with the writer.
In my experience, I find I get bored when information is poured into me in the beginning of the story. I just want the story to get started. But remember readers are all different and some prefer the details of the characters and plot placed for them in the beginning. If you can keep your reader interested while you spill out all your character’s information, I say more power to you. Remember this also has to do with your character. If they are the type to lay it all out on the line then do a reveal in the beginning. If they are more the type to get the action started and explain later than start with action.
Remember this is your character’s story and they have a way of telling you how they want their story told. So choose a POV and keep writing.
