I am looking for a saying which means "too much of something makes the value of it decrease, or sometimes people doesn't value it at all". I know there is a phrase "to take something for granted", but I want something like a saying or a proverb.
I thought about it and came up with this one. Though it's not a proverb, it might convey the meaning I intend to convey.
"Too much bread makes one lose one's hunger."
Tell me if this is understandable, or if you have any better alternatives.
