How you measure things will end up ruling you.
Perhaps that’s where we derived the name “ruler” for something that can measure something for us.
However you’re measuring whatever you’re measuring take some time to focus on the depth and not just the width.
Yes we see width, but we remember depth.
Width: look at what I did.
Depth: look at what this meant.
Choose wisely.
