Everyone should take the saying “try and try until you succeed” to heart, for it is in our failures that we find ways to improve ourselves. Take for example this dog, who did not quit until he got his prize: the lush head of cabbage sitting innocently on the table. The cabbage was so near, yet so far—just an inch or two (or less) away from his excited jaws. In the end, he succeeded in getting it, but not without going through a number of failed attempts. See his cabbage quest in the video below.
