1. acting or progressing in a way that will likely lead to success/failure
be back on the right track
A track is a line of fixed rails that the wheels of a train follow. So, the right track will lead you to your chosen destination, the wrong track will lead you somewhere you don't want to go. This expression refers to following the right or wrong direction towards a chosen goal or desired outcome, which is why it is more commonly used in a professional environment. A similar phrase is 'go about something in the right/wrong way,' or to 'be on the right/wrong path.'
