"Waste not, want not" means that if you use things carefully and don't waste them, you won't need or want more of them later. It is a saying that encourages people to use resources wisely and not take things for granted. It can be used in any situation where one is being wasteful, encouraging them to be more efficient and responsible. For example, if you have food left over from a meal, you could say, "waste not, want not" to imply that the food should not be thrown away, as it can be used later or given to someone else who needs it.
