Human Factors
I departed BQ1 on Runway 31 and announced my attentions to return for an approach to Runway 13.  After maneuvering to final for 13 I started my approach.  I noticed an airplane pull out on the runway and start to back taxi.  Since I was already low and approaching the numbers on Runway 13; I added full power to accelerate and began a climb before reaching the other aircraft.  I also side stepped to be over the parallel grass runway.  I passed above and to the left of the other aircraft by a few hundred feet.Although the winds were light and approaches had been made in both directions within the hour; it was not a good choice to depart one runway and then perform an approach to the opposite runway.
GA pilot reported a conflict during final approach to BQ1 non-towered airport resulting in a go-around.
