off course
1. Literally, in the wrong direction or away from the intended course. Could you check the map? I think we're a bit off course.
2. By extension, going against or straying away from an established plan or the correct or intended course of action. I got a little off course after my girlfriend broke up with me, so I'm trying to get refocused on my studies. This project is so off course that I don't know if it's worth continuing.
