Which of these is correct – “Running on circle” or “Running in circle”? All I want to express is that we are doing same work again and again.
go around/round in circles also run around/round in circles
to use a lot of time and effort trying to do something, without making any progress.
If you want to be specific about doing things again and again with no good outcome, choose go around/round in circles [on the same page of that link].
go around/round in circles – if you go round in circles when you are discussing something or trying to achieve something, you do not make any progress because you keep going back to the same subjects or the same problems.
