The goal of all living things is survival, life, and also the maintenance of the species play an important role. That's what drives them.
This is exactly what beavers do. Although they can make a person's life and environment bitter with their work, everything is just a matter of point of view. From their point of view, they are only about getting food, building their own dam, where they can raise their offspring.
Beavers do nothing but listen to their instincts and do their own beaver-like thing.
