Antonyms for the phrase "bides time" include impatient, hasty, and impulsive. These terms describe individuals who do not possess the patience or self-control required to wait for the appropriate moment to act. Impatient individuals are easily frustrated when things do not occur as quickly as they would like, and as a result, they often make rash decisions that they later regret. Those who are hasty tend to act without forethought or consideration of the consequences, whereas impulsive people act on their emotions without weighing the potential outcomes. In contrast, those who bide their time exercise restraint, waiting until the opportune moment presents itself before taking action.
