See my hub "Using a Memories Graph to Generate a Story Idea" for one approach to using your own life experiences to generate fiction writing prompts. You graph the emotional highs and lows of your life and then, choosing one of them, you use your memory of your emotions as a prompt to draft a scene in a story. Suppose, for instance, that once upon a time you were engaged and were jilted. Begin with that memory of confusion, rejection, and heartache and let your imagination "bring on stage" a character, perhaps long ago and far away and in many ways different from you, in a situation that will cause him or her such emotions.
Another technique is to choose an object that is in your sight and imagine that object in another setting, perhaps long ago and far away, and imagine characters interacting with or near it.
The two techniques can be combined. I might, for instance, choose a floor lamp in my Kalamazoo apartment. I might imagine such a lamp in a Chicago flat circa 1949. A young woman lives there with her cousin. Her boyfriend has come to take her to the movies as usual on Saturday night, but she is at a roller skating rink with another man, and the cousin sends the boyfriend away with a lie.
I got the book HUMANS OF NEW YORK STORIES by Brandon Stanton for Christmas. Stanton is a New York photographer who goes around taking photos of people and asking them personal questions. He then posts photos and quotes on his blog and on his Facebook page and eventually gathers them into a book. Many of the photos and quotes are poignant and would, I think, make good writing prompts. Browse through a copy in a bookshop and see if the glimpses into personal experiences of love found or lost, of wisdom gained the hard way, of innocence, of crime, of grief, and so on might work for you as writing prompts.
