This is the message of many historical icons such as Abraham Lincoln and Helen Keller who have been successful in their endeavors through these two master keys. Abraham Lincoln was mostly self-educated but still managed to be the 16th President of the United States to abolish slavery and modernize the government. Similarly, Helen Keller became the first person with deaf blindness to gain the degree of Bachelor of Arts. She dedicated her life in helping the lives of other disabled people around the world. Well, she is the founder of the American Foundation for the Blind.
Many people have experienced this state of balanced attitude, who are now able to see failure and success as motivators to move ahead, instead of halting and falling backward.
