There Are Questions In My Head

Somehow, when you look at me, I feel like I can do anything.
I don't know why you look at me like that;
like you believe in me.
You barely know me.
You tell me to speak up and let the world know my thoughts.
(Okay, so maybe it was just a class room,
But it feels like the world sometimes),
And you make me feel like what I say has value to it.
But again,
you barely know me.
So, how are you so sure?
How are you sure it's of worth?
Why do you believe in me when I can't believe in myself?
