Bite off more than one can chew
Meaning
To attempt a task or commitment that is too large or difficult for one's capacity.
Origin
Imagine sitting down to a feast, perhaps after a long day, and in your eagerness or hunger, you carve off a piece of meat far too big for your mouth. You chomp down, only to find it unmanageable – too large to chew comfortably, too much to swallow. That vivid, slightly embarrassing struggle with an oversized mouthful is the literal bedrock of "bite off more than one can chew." This universal human experience of overestimating one's oral capacity naturally evolved into a powerful metaphor. By the 19th century, the image of someone metaphorically choking on their own ambition had become a common and crisp way to describe anyone who had taken on a task far beyond their abilities, moving the struggle from the dinner table to the grander stage of life's challenges.
Examples

- Don't bite off more than you can chew by volunteering for every committee; you'll burn out quickly.
