The phrase "coming to a decision" implies that someone is making up their mind about something. Its antonyms could include "remaining undecided," "leaving it open," "indecisive," "unclear," or "ambiguous." In some cases, these options can be a sign of flexibility and openness to different ideas or opinions. However, if someone is consistently leaving decisions unresolved, it can be seen as a lack of commitment or leadership. It's essential to strike a balance between taking time to make important decisions and avoiding being too indecisive. Ultimately, having the ability to make sound choices is crucial to success in both personal and professional endeavors.
