Here is my meaning of Hellen Keller's quote:
It means that by using my voice I can do something. I may not be THE one but AT LEAST I AM one. I know that I can't do everything but the thing is, I CAN do SOMETHING. I will do what I can do to make a difference.
I don't know if that make sense or not, I have to give this speech tomorrow and I'm kind of struggling with the conclusion.

Your interpretation of Helen Keller's quote is quite insightful and captures the essence of her message. Helen Keller, who was deaf and blind, advocated for using one's voice and abilities to make a difference, regardless of the scale. In the conclusion of your speech, you can reiterate this idea and emphasize the importance of taking action, even if it may seem small or insignificant. Here's an example of a conclusion that incorporates your interpretation:
"In conclusion, Helen Keller's quote reminds us that we all have the power to make a difference, no matter how big or small. By using our voice and utilizing our unique abilities, we can contribute to positive change in the world. It may not always be easy, and we may not be able to solve every problem, but what matters is that we take action. As Helen Keller said, 'I am only one, but still I am one. I cannot do everything, but still I can do something.' Let us remember these words and strive to do what we can, knowing that our efforts, no matter how small, can create a ripple effect of change. Together, we can make a difference."
