When starting a new novel I find it hardest to express my characters personality through words. I don’t know my character, nor do I know how she would talk, how she would act and so forth. It’s important to know your character, but it’s also important to get your point across to your readers. One of the main choices you will make will be the point of view in which the book is written.
Is it going to be written in third person? If so, you might struggle with emotions. You have to be careful as you could get caught up in “telling” instead of “showing”. As in, your character won’t be telling his/her own feeling, that non-existent narrator, who hides behind the red velvet curtain, will be. You have to be careful not to throw more into the plot and abandon your character’s emotional development.
How about first person? You wont be in danger of delaying your character’s emotional development until the last fifty pages (when you remember your character has to go from point A to point B just like your plot) but you could get lost in all the drama that is your protagonist’s life and not focus on your main objective: to have a flowing story with both your best story telling and your character’s unique personality. (You did create him/her after all!)
Point of view isn’t just about which way to tell your story, it’s also about using your strengths. What is the best way for you to tell a story. Are you better using the Dear Dumb Diary method or are you more of a straight forward kind of writer who finds it easier to write from your heart to your character’s? If you’re the second, you might want to think about first person POV!
