bit off more than one could chew

Took on excess

To bite off more than one can chew is to take on more than one can handle—committing to a task, responsibility, or challenge that exceeds one's capacity.

The image is of someone cramming too much food in their mouth to manage.

I thought I could renovate the house myself, but I bit off more than I could chew.

The past tense form appears in reflections on overcommitment.
