Can't Stop Now

I noticed tonight that the world has been turning
While I've been stuck here dithering around
Well I know I said I'd wait around till you need me
But I have to go, I hate to let you down
But I can't stop now
I've got troubles of my own
Cause I'm short on time
I'm lonely
And I'm too tired to talk

I noticed tonight that the world has been turning
While I've been stuck here withering away
Though I know I said I wouldn't leave you behind
But I have to go, it breaks my heart to say

That I can't stop now
I've got troubles of my own
Cause I'm short on time
I'm lonely
And I'm too tired to talk

No one back home
I've got troubles of my own
And I can't slow down
For no one in town
And I can't stop now

And I can't slow down
For no one in town
And I can't stop now
For no one

The motion keeps my heart running
The motion keeps my heart running
The motion keeps my heart running
The motion keeps my heart running
