"Calls it quits" is a common phrase used to describe the act of ceasing or ending something, like a job or a relationship. The antonyms of this phrase are words that imply the opposite, such as continuing, persisting, enduring, or persevering. Instead of quitting, people can choose to carry on, persist, or persevere through the difficulties they face. These antonyms suggest that sticking with something, even when it's hard, can lead to success and personal growth. It is essential to keep pushing through the difficulties and keep striving for progress rather than giving up and quitting everything.
