From my own experience, my Hero wrote his "Personal History", but it was a factual history, i.e. I was born... He did not include any of his "stories" of what made him the person he was. His good fortune was I was a good listener and in my grief, I wrote the stories that made him come alive again to his children and will help his grandchildren to know him.
What help me to write his stories was I found a group called GeneaBloggers on the Web and their memes gave me the platform to write those stories. GeneaBloggers has transitioned into GeneaBloggers Tribe, but still has the prompts for those that have a hard time zeroing in on a topic or thought.
Another point is, if you procrastinate, you might lose the capacity to remember and or write those personal memories. Just saying...
I, personally, am going to pick up with my stories now and if it triggers one of the Hero's then I will write that too. Please, if you have only been concentrating on other's stories or professional instruction, teaching, et cetera, pause occasionally and begin writing your own stories. This is a plea on your behalf and those that come later.
PS Did you ever think that your story that includes others, rarely is a story about only one person, could help another learn about their family member too.
'Til next month... keep writing.
