Measured setup

I'm trying to juggle too much at the moment and some things are falling behind. I'm going to have to park some of my activities until I get a breather!
This is an exercise in measuring from SketchingNowFoundations. While I'm not one for measuring (I just don't have the patience), I have to admit that it's very effective. I should probably do more of it, as I would waste less time with sketches that don't work out. Will I stick to it, though?
