“If you can’t measure it you can’t improve it.” Peter Drucker

You need to track the things you want to work on, not just rely on a sense that “ehh I am getting healthier”

  • Tracking things makes you subconsciously change your behaviour? (TODO find that article about how weighing self everyday makes people adjust their food intake)
  • You don’t really know unless you take the scientific approach: eliminate other variables as much as possible, repeatedly test (with a control) and see if the effect is repeated.

Opposing this is Goodharts Law because trying to optimize an imperfect measure = end up working towards a different direction than your actual goal
