shoots oneself in the foot

Undermines own success

To shoot oneself in the foot is to sabotage one's own efforts through carelessness or poor judgment—to damage your own cause while trying to advance it.

The image is of someone so inept with a weapon that they injure themselves: He shot himself in the foot by insulting the interviewer.

The phrase emphasizes that the harm is self-inflicted and avoidable.
