What do I like to write about?

I like to write personnel narratives. I like to write about my experiences because most of the time it is fun to sit and think about the past. I also like to write about past experiences because it is easier to write about. When i write fictional pieces i have a tendency to change things half way through the piece and end up confusing the reader. With past experiences there is nothing creative about it i just write from what i remember and turn my writing into a movie in my head remembering exactly how everything happened. When writing creative pieces it takes me a long time to plan out how the story will happen and with a narrative nothing ever really changes because i cant change what already happened.
