How does "I came, I saw, I conquered," from The Story of My Life, prove true in Helen Keller's case?

In chapter one of The Story of My Life Helen Keller talks about her life before she was left blind and deaf after a terrible illness as a baby. When she says "I came, I saw, I conquered" she is speaking about how she impressed her parents and captured their hearts "as the first baby in the family always does." Every parent is overawed by his or her children as babies, especially as they reach milestones sometimes sooner than expected, and Helen's parents are no exception.

After her illness things change and life for Helen becomes very difficult. However, her parents support her and do whatever they can for her. This book and the very successful and fulfilling life that Helen goes on to have are testament to her perseverance, patience and level of intelligence. Helen could not have known how prophetic those words would be. 

Once Anne Sullivan comes into Helen's life, in chapter two, Helen finds escape from her "silent, aimless dayless life." In chapter four she acknowledges that "the most important day I remember in all my life" is the day Anne arrives. From that day forward "everything that could hum, or buzz, or sing, or bloom had a part in my education" (chapter seven). Helen's incredible ability to "learn from life itself" is what ensures her success. 

Helen faces each challenge and makes it a learning opportunity. She is in a tree when lightning strikes, she is washed underwater by a wave, and she and her sister get lost, yet Helen refuses to let any of these events stop her. Rather she insists they contribute to her education. Helen graduates from college, which is impressive for any woman from that era, and uses her own situation as a possible learning experience for others by writing this book. She will go on to be a motivational speaker and to write several other books.   

The main goal of this book is to help others who may experience tough times and to help them find their way through the difficulties in spite of obstacles. Helen wants others to understand that if she can do it then anyone can.
