This is how I pick the subject matter for each short-short (or flash) autobiographical story that I write.
My mind is a giant field in the summer sun. There are colorful flowers on top of it. There are also, nickels and dimes that are hidden by the grass. I always want to write about the flowers because they stick out, seem so dramatic. But if I just move around the field a bit, the unexposed nickels and dimes will shine. I am drawn to them. This is how I pick my subject matter. They are moments in life, that when first thinking about them, seem dull. But if you look at it another way or at least give it a shot, they turn out to be turning points in how your philosophical outlook was formed. This is where I have been finding inspiration, in the little moments.
