The antonym for "taking one time" could be either "repeating" or "continuing." When someone takes something one time, they do it once and then move on to something else. Repeating suggests doing the same action over and over again, while continuing suggests something ongoing without a defined endpoint. In both cases, the focus remains on staying consistent or persistent. If someone is always repeating a certain task, then they may develop a pattern of behavior or habit, while someone continuing with something may be pursuing an ongoing goal or objective. Whatever the case, these antonyms suggest a different approach to the original action of taking one time.
