being one's own worst enemy

Undermining your own success

Being one's own worst enemy means sabotaging yourself through your own habits, choices, or personality traits.

The phrase acknowledges that external obstacles often matter less than internal ones—procrastination, self-doubt, impulsiveness, or stubbornness that undermine your own interests: He's his own worst enemy when it comes to relationships.

The expression implies the damage is preventable but persistent.
