Memory can be your best resource when you write. You can write about specific memories, or use those memories to create a memory for your characters. Usually, no one will recognize them as specifically yours, unless you are writing a memoir, then they will.
Memories can supply you with physical places to set your stories. Memory can also help you with resources.
Sometimes we use our memories to time travel to our childhood or early adulthood. You can use that to help with your character trying to put a book together or when they need to be a witness to something.
Memories are powerful things and you can use how your memories make you act or react when writing a character or interviewing someone for a non-fiction piece.
And now, I will exit to the tune of Memories from the play Cats.
