Almost everything worth improving is easy to measure in isolation and hard to measure against anything else. You can track sleep, or savings, or hours of deep work and each number will go up honestly while the life behind it gets narrower.
These seven exist so that the question is never just how one line is doing, but what it cost the other six.
I do not score them. Scoring turns a framework into a dashboard, and a dashboard invites you to raise the number rather than examine the thing. What I do instead is run down the list every so often and ask a single question of each: what has this one been paid, and what has it been paying for. The answer is usually obvious within a few seconds, and the pillars that stay silent are the ones worth looking at.
The list earns its keep when two of them are in open conflict, which is most of any given month. Work that serves Prosperity is almost always taken out of Vitality or Harmony. Time given to Clarity is time not spent on Mastery. Having the seven named does not tell me which way to decide. It stops me from pretending the decision was free, and it makes the bill arrive at the same time as the purchase rather than a year later.
