defying gravity

Something has changed within me
Something is not the same
I'm through with playing by the rules
Of someone else's game
Too late for second-guessing
Too late to go back to sleep
It's time to trust my instincts
Close my eyes: and leap!

It's time to try
Defying gravity
I think I'll try
Defying gravity
And you can't pull me down!

- "Defying Gravity" from the musical "Wicked" as performed by Kristin Chenoweth
