write checks one can't cash

Promise beyond means

To write checks one can't cash is to make promises or claims that exceed one's ability to deliver.

The metaphor comes from writing a bank check without sufficient funds to cover it.

Someone who talks tough but can't back it up, or commits to projects beyond their capacity, is writing checks they can't cash: Don't let your mouth write checks your body can't cash.
