Being one's tail implies being someone's follower or subordinate, always hanging around and imitating their behavior. Antonyms for this phrase could include independent, leader, or innovator. Being independent means you are self-reliant and able to make your own decisions without relying on someone else's guidance or opinions. A leader is someone who sets an example for others to follow and takes charge of situations. An innovator is someone who thinks outside the box and creates new ideas or methods. These antonyms suggest a sense of individuality and originality, which contrast with the idea of being one's tail.
