Maybe you are taking a very short trip in the car.
Maybe you are someone who has small bits of spare time throughout your day.
Maybe you have a short attention span.
For any or all of these reasons you may want to try audiobooks that are collections of short pieces. They could be traditional short stories or short true stories that inspire you or make you laugh. In any case, it doesn't take much time, as compared to a full length book, to get from the beginning to the end of a complete work.
