The phrase "goes amiss" can be described as something that has gone wrong or not according to plan. Its antonyms would be "goes right", "goes well", "succeeds", and "prospers". When something goes amiss, it may cause a setback or a failure, but by using these antonyms, we can describe a positive outcome, such as a goal being achieved or a plan going smoothly. In many situations, it's important to focus on the positive outcome rather than just dwelling on what went wrong, and these antonyms can help us do that.
