Our character is shaped as much by our failures as it is by our successes. Our eyes are placed in front because it is more important to look ahead than look back. Our five senses are incomplete without the sixth - a sense of humor. Our greatest glory consists not in never falling, but in rising every time we fall. Our toaster works on either AC or DC, but not on bread.
