I have always been told from the off that I should be thinking three or four steps ahead of the aircraft.
Therefore contemplating whether I am on the correct runway once I have already continued from the hold is asking for trouble.
Personnally I've already thought about wind, runway, checks etc before I even call for departure, including what I will do if I have an engine failure during or shortly after take off. I am then free to enjoy the flight without having to work my backside off when there really is no need to.
