Oh, I must stop these doubts, all these worries
If I don't I just know I'll turn back
I must dream of the things I am seeking
I am seeking the courage I lack
The courage to serve them with reliance
Face my mistakes without defiance
Show them I'm worthy
And while I show them
I'll show me
I have confidence they'll put me to the test
But I'll make them see I have confidence in me
...I Have Confidence, The Sound of Music
