I am not sure when or where I heard this saying...yet it is a mind set I constantly tell myself...similar to Recycle, Reduce, Reuse. This type of mentality has been passed down from my mom, who learned it from her parents. My grandparents saved and repurposed just about everything...and the reason I was told they were like that is due to the fact they lived through the Great Depression.
Having been through the Great Recession, this way of thinking appears to be making a come back...and it is great to see other being conscious of the importance to be mindful of our resources.
