You're tracking 20+ metrics, spending hours in analytics, and still can't answer the one question that matters: "Is this working?" The problem isn't lack of data, it's data overload. When everything is a priority, nothing is.

The solution isn't more sophisticated tracking, it's radical focus. In this post, I reveal which metrics deserve your attention at each growth stage, which ones are distracting you from real progress, and how to build a lean measurement system that drives profitable decisions.
