Drive is focus and energy applied towards work.
There are many kinds of Drive: social drive, tracking drive, prey drive, bite/kill, stalking, and food to name a few.
Social drive, prey drive, and bite/kill are the types of Drive most active in the game of disc dog freestyle, and are all fairly desirable. Stalking and tracking drive can be tough distractions.
Drive should not be mistaken for Arousal. Arousal is energy that is unfocused and not easily applied towards work.
