The byline of this chapter is “If you can measure it, you can improve it,” a well known quote adapted from Lord Kelvin (whoever that is) and used in everything from business to sports and more.
In the real world, practical evidence of this truth is all around us if we take the time to think about it. One of my favorite and most apt examples is of a physical therapy visit I had a few years ago. It was my final visit for my wrist, broken a couple of months earlier from my first road crash. What’s the first thing they do in PT? They measure. What’s the last thing they do? They measure. On my last visit, all my measurements improved except for one. Truth be told, it was the only thing that I hadn’t done my ‘homework’ for. The poor results then made me ultra aware of its weakness, and so I became committed to turning that around. I worked the wrist in the specific direction and manner that I had slacked off on (in other words I did my homework properly and consistently) and in just four days, upon my return and re-measurement, I had increased my joint’s mobility by 14%!
