called "tolerance to frustrations". I once had a professor of sociology in college who studied Alaskan culture focusing on the Indians (eskimos or inuits). He once sat in an igloo in the middle of winter watching an infant try and try to move some large object. When he went to help the father motioned him away "let the boy do it". Concluding the interview some hours later the child had just begun to move the object. The elder Inuit told the professor life will be full of frustrations as the child ages and he needs to learn tolerance. That cub in the video could give us all a lesson too.
