haste makes waste

Prov. You do not save any time by working too fast; hurrying will cause you to make mistakes, and you will have to take extra time to do the job over again. Fred: Hurry up and get my car fixed. Alan: Don't rush me. Haste makes waste.

Proceeding too quickly can spoil an enterprise, as in Stop trying to rush through three things at once-haste makes waste, you know. This rhyming warning, first recorded in this exact form in 1575, was in John Ray's 1678 proverb collection, where the full text was: "Haste makes waste, and waste makes want, and want makes strife between the goodman and his wife."
