Something like a warning

"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.
I'm through accepting limits 'cos someone says they're so.
Some things I cannot change but 'til I try I'll never know."
- "Gravity", Wicked Soundtrack
