You can’t make an omelet without breaking a few eggs
Meaning: You cannot achieve a goal without sacrificing something else.
Origin: The phrase’s origin is attributed to one François de Charette, a French naval officer at the time of the French Revolution. He led royalist troops in the Vendée Region, participating in numerous battles, as well as becoming an expert in guerilla warfare. When Charette was eventually captured, he was ordered to account for the many deaths the caused in the course of battle and reportedly proclaimed, “on ne saurait faire d’omelette sans casser des œufs“ and it’s been used as a fair-to-poor excuse for wanton destruction ever since.
