"Quit cold" is an expression that means to suddenly stop doing something or to end a habit abruptly. Antonyms for the term "quit cold" include persistence, perseverance, and continuation. When we persist, we continually pursue our goals even when faced with challenges, obstacles or resistance. Similarly, when we persevere, we show endurance and dedication in our efforts to achieve a desired outcome. Continuation, on the other hand, refers to the act of carrying on with something that has already been started, or maintaining a habit or a routine. So, instead of "quitting cold," we can strive to cultivate persistence, perseverance, and continuation for long-lasting success in our endeavors.
