Some ideas of what to include in your story.

Don't forget to write your own history!
This is a very important item to be able to pass on to your
children and grandchildren.
Here are some things for you to consider:
1) House/Place where I was born.
2) Circumstances surrounding my birth.
3) Tell about my parents, brothers and sisters (include stories
about them).
4) Childhood health conditions (diseases, falls, and accidents).
5) Playmates and amusements.
6) Religious practices.
7) Economic conditions (times when food and money were scarce).
8) School, teachers, studies.
9) My chores at home.
10) Sports that I took part in.
11) Courtship and marriage.
12) My husband/wife (how we met, why I love him/her)
13) Our children (differences, traits, habits, character, talents,
hobbies).
14) Our home(s) (where we lived, why we lived there).
15) Political activity.
16) Good books that I have read and why I consider them good.
17) Recreation (singing, dancing, sports, etc.)
18) How many times I have moved in my lifetime and why.
19) Travel ad vacations.
20) Children.
21) My hopes for the future.

Write simply and to the point, like you are talking to someone.
Add pictures and remember to include dates.

3) What were you doing the day John Kennedy was shot, 22
Nov. 1963?
4) What was your bedroom like as a child?

You can write short things about yourself when you have a spare
moment, over lunch, at the doctor's office, while waiting
for service somewhere. Write as things come to you.
Then, as you have more time, you can put it all together
into your story.
