"Do I Dare" is the song in the Sofia the First episode, "The Secret Library". In the first half Sofia voices her doubts about her ability to be the storykeeper and in the second half she voices her resolve to do so.
Even though I've just begun
To somehow get these stories done.
How can I aim so high
When I've let down everyone?
Now I feel like I'm a fake
Thinking there must be some mistake.
I can't see why she chose me
When I don't have what it takes.
Oh, can I lead the way?
Make everything okay?
Just how am I supposed to save the day?
And what is there to say.
When my chance has flown away.
Why'd I think that I could be the one to save the day?
I may not know exactly how I'll do it.
But I know that I can free them
If I put my heart into it.
Oh. I can lead the way.
Make everything okay.
I'm the one that has to save the day.
And there's nothing more to say
'Cept up, up and away.
Cause I believe that I will be the one to save the day.
