Narrative:

Sna tower instructed me to hold short of runway 19L at taxiway K. I inadvertently taxied into position and held. Nobody had to go around, and luckily nobody was taking off. The tower cleared me for takeoff shortly after. In the future, I will assure myself that paying attention to the radio calls are very important, and not make this mistake again.
