Idiom: (Get) back on track
Let me pick up where I left off yesterday.
Of course, after someone taking part in a conversation goes off on a tangent, they have to get back to the subject at hand or get back on track again.
To get back on track means to begin talking about the original subject of the conversation.
It can also mean to return to the regular schedule.
So, if we are in a conversation and then we suddenly start talking about a different subject, we need to get back on track again.
Also, perhaps we are at the office working on an important document, and due to a storm, we lose power.
Well, that means we are going to fall behind in our planned schedule, and when the power is reconnected, we will have to work a little harder, or maybe longer, to get back on track.
