The word "wast good enough for" implies mediocrity and dissatisfaction, so its antonyms would preferably have positive connotations. Some suitable antonyms might include "exceptional," "outstanding," "remarkable," "extraordinary," "superb," "excellent," "first-rate," "brilliant," "splendid," and "supreme." These words suggest excellence, superiority, and high quality, which are far removed from the feeling of underperformance and dissatisfaction that "wast good enough for" represents. Using these antonyms helps to convey a sense of pride and accomplishment, rather than settling for less. So let's elevate our language and aim for excellence instead of settling for mediocrity!
