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 Well 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
