I Used the Japanese Concept of "Mottainai" to Lower My Grocery Bill - And Saved $127 in a Week
Briefly

Mottainai is about respecting resources by avoiding waste, reflecting a belief system that encourages mindfulness about consumption and sharing responsibly.
'At school [in Japan] we were taught to use a resource as if it’s the last one, even if there’s plenty,' recalls Chen.
Using only what you need is a tenet of mottainai, applied not just to food but everyday resources like tape and running water.
From a young age, throwing away food was seen as a big no-no; mottainai teaches to take only what can be consumed.
