Deciding on the narrative point of view means that an author must choose
a. how long the story is going to be.
b. who is telling the story.
c. where the main character is from.
d. when the story is taking place.

its b whose telling the storry. narrative POV is perspective in which the storry is told.

(ill try to explain it rather than make my own, since its easier)

draw a simple timeline can be drawn out like the kind you'd see in history documentaries.

it shows 10 major events in your life (like the year you were born, when your sibling was born, etc.)

now make those events more specific in between. my example:

<      |        ---      |           |          |      >    etc.

2004           2005                     2009             2010

birth           sister's                     first         end vacation

                    birth                   vacation

you can also add months of the year.

then add small details in between these events, like first tooth or new clothes.

now you can make this sort of one-word-summary of some events. something like 2009-2010 "astonishing" or whatever.

based off of this, you then make a narrative story of your life history. yknow, the kind thats from a 3rd person POV.

use a title thats interesting and unique (like amazing path of life or something, i dunno)

it says it has to be at leat 3 paragraphs, each with 3+ sentences. so it shouldn't be that long after making the timeline!

in a way, you could consider this your "life novel" but its in a story fashion.

the timeline is there to make it easy to see the big picture.

just comment if you need anything else :D
