It is not specific to humans. Birds and cats have this urge to discover. That overwhelming desire to open the closed door or to look around the corner. That is called curiosity. To satisfy this need should remain a lifelong quest. Because then one is always occupied, one is never bored, always learning, and always trying to cure one’s own ignorance. A large task for me. Happy New Year.
