In The Miracle Worker, what are the three things Annie tells Kate she (Annie) has going for her?

Kate is surprised by Annie's youth. She is also understandably concerned because Annie has never taught before. James suggests that Annie may end up being a burden on the family, and Captain Keller is shocked when he hears that Annie herself was once blind: "The blind teaching the blind?"
Annie seeks to reassure Katie that even though she (Annie) is young and relatively inexperienced, she has three important advantages over any other teacher.
1. She is young and has energy. This will be vital for dealing with a student with the emotional issues and physical strength of Helen.
2. She is smart and has studied the research. Annie was taught in one of the most progressive schools for the blind of the time. She has experienced the success of their techniques personally and has looked deep into the research behind the techniques.
3. Annie has been blind and has empathy for Helen. Annie understands the difficulties and emotional toll of being blind. She knows how to empathize without pitying. Helen has been spoiled by too much pity and indulgence. Annie knows that that kind of treatment is the worst thing for Helen.
