is one's own worst enemy
Defeats oneself consistently
Someone who is their own worst enemy engages in self-defeating behavior—sabotaging their own success through poor choices, bad habits, or counterproductive tendencies.
The phrase acknowledges that external obstacles matter less than internal ones: He's talented but he's his own worst enemy—always missing deadlines.
Often said with a mix of sympathy and exasperation.
