헛수고하다, 제자리걸음하다

to spend a lot of time and effort doing something that achieves nothing

:
We've been chasing our tails all day trying to fix this bug, but we're no closer to a solution.
우리는 이 버그를 고치려고 하루 종일 헛수고했지만, 해결책에 전혀 가까워지지 않았어.
If you keep chasing your tail with minor issues, you'll never get the main project done.
사소한 문제로 계속 헛수고하면, 주요 프로젝트는 절대 끝내지 못할 거야.
