Wondering what to do next

I've learned to slam on the brake
Before I even turn the key
Before I make the mistake
Before I lead with the worst of me
… Give them no reason to stare
No slipping up if you slip away
So I got nothing to share
No, I got nothing to say
… Step out, step out of the sun
If you keep getting burned
Step out, step out of the sun
Because you've learned, because you've learned
… On the outside, always looking in
Will I ever be more than I've always been?
'Cause I'm tap, tap, tapping on the glass
I'm waving through a window
I try to speak, but nobody can hear
So I wait around for an answer to appear
While I'm watch, watch, watching people pass
I'm waving through a window, oh
Can anybody see, is anybody waving back at me?
… We start with stars in our eyes
We start believing that we belong
But every sun doesn't rise
And no one tells you where you went wrong
… Step out, step out of the sun
If you keep getting burned
Step out, step out of the sun
Because you've learned, because you've learned
