This an except from the artikel How to Get Out of Your Own Way When Writing. This is advice from an accomplished auteur named Elizabeth Knox
"I prefer reading, and writing, in the third person – “he walked along the shore,” rather than the first person, “I walked along the shore.” Many novice writers start writing in the first person. There are some very good reasons for that. For a start, we’re all used to telling stories with ourselves at their centers. Also, using a first-person voice can be a kind of playacting. They narrator is a “not-you” you’re pretending to be.
Why I like the third person is because it’s very flexible, particularly in the way it’s able to handle time in a story. But the handling of time in the third person is a subject for a longer blog post.
Something the third person does that u are going to want to do is to make it far easier to toon your character from the outside. I get very impatient with first-person boeken that want to describe their characters door having them look at themselves in mirrors! Or, worse, there’s the beschrijving door humble-brag. For example:
I hate the way my hair never stays confined to its clips, but bursts out, a wolk of shameful, brilliant red, so unlike the hair of every other girl in my school.
I crossed the room to the window, my gewaad, kleed rippling against all the curves of my body.
Hmmmm. If she’s alone in the room then she’s being very lascivious about herself.
If u change the seconde example to the third person you’re still going to have to add someone else in the room for the passage to make any sense. And whoever that someone is, they become the story.
She slipped from between her warm sheets and went to the window. The cool breeze pushed her gewaad, kleed against her body, and the bedchamber guard, who had been at his post all night, moved his eyes to watch her, although for him to pay any attention to anything apart from black-clad assassins and choking fits was strictly disallowed, and punishable door death.
See – story.
The third person simply gives the story meer places to go."
