A sage once reduced all virtue to the golden mean. Push right to the extreme and it becomes wrong: press all the juice from an orange and it becomes bitter. Even in enjoyment never go to extremes... If you milk a cow too much you draw blood, not milk.
Baltasar Gracián, 1647 (tr. Joseph Jacobs, 1892)
Everything good has a point past which continuing extracts something worse: the favour asked once too often, the joke stretched one round too long, the discipline pushed into punishment, the visit extended past welcome. The images are deliberately physical, the bitter orange, the bled cow, because the mistake is physical too: not knowing when the good part has been fully collected. This maxim is the household cousin of leaving-while-winning: it governs small daily extractions rather than grand exits. The skill is sensing the last good pull, and stopping one before it.
Practice
- In favours and goodwill, stop well before the visible limit; the relationship that never feels drained keeps refilling on its own.
- In pleasures, end at the peak on purpose: the holiday a day shorter, the gathering left while it is still warm. What you keep is the memory of wanting more.
- In demands on yourself, watch for blood in the milk: when discipline starts producing dread instead of output, the extraction has gone too deep (maxim 33 audits the leases).
Use this when
- Use this on your most reliable resources, the helpful colleague, the generous relative, your own stamina, because reliability is exactly what invites over-drawing.
- Use it hosting and visiting; the guest who leaves early is invited always, the one who drains the evening is invited carefully.
Ignore this when
- Don't use moderation as a reason to under-deliver on real commitments; the maxim governs extraction, not effort owed.
- Don't apply it to compounding that harms nobody; the SIP does not bruise from running long.
A picture of it
Two nephews had the same generous uncle. One asked rarely, repaid visibly, and always left the account of goodwill fuller than he found it; decades later the uncle's door and wallet both still open for him unasked. The other treated the uncle as a facility: every shortfall, every deposit, every guarantee. Nothing was ever refused, and something was lost each time anyway. The uncle now greets him warmly, hears the request coming in the first minute, and has learned to be unavailable. Same cow. One nephew took milk. The other drew blood.
Stop at the sweetness. Whatever comes out after that, you did not want anyway.
