LAW 10: INFECTION: AVOID THE UNHAPPY AND UNLUCKY

The powerful are deliberate about whom they let near, because proximity to chronic misfortune is rarely neutral — it pulls you into the drama and attaches their failures to your name.

The mechanism is psychological and reputational at once. Chronic complainers and self-pitying personalities recruit rescuers and scapegoats: join their story and you inherit responsibility for an ending that almost never resolves in gratitude. Their crises become your crises; their reputation for trouble rubs off on yours. Greene's sharper point is that this infection works through sympathy — the very generosity that makes you want to help is the channel through which the misery enters and spreads.

Greene's illustrations contrast the infectors with their opposite: figures whose poise, energy, and good fortune lifted everyone around them. He counsels associating with the happy and the fortunate not out of snobbery but out of self-preservation and compound advantage — because their confidence and luck are as contagious as the other kind, and they open doors rather than closing them. Choose circles where competence and optimism are the norm, not the exception.

Reversal — there is no reversal to this law. Greene states it flatly: the infection is real and the only defense is distance. The one nuance is that you need not be cruel; you can extend limited, bounded help, but you must never let it become proximity, dependence, or shared fate.

The applied takeaway is to audit your associations as carefully as your investments. When you must deal with the chronically unhappy, keep boundaries strict — limited time, clear terms, no emotional debt — and never let sympathy become entanglement. Sympathy can exist without proximity. Helping someone should not cost you your stability, your focus, or your future. Be selective, not heartless, and protect the energy and reputation that everything else you build depends on.

Greene frames the positive corollary as deliberately as the warning: just as misery infects, so do confidence, energy, and good fortune, and the powerful court the company of the fortunate precisely to absorb that upward pull. The practical defense is not isolation but selection — keep your inner circle composed of the competent and the buoyant, and treat your associations as decisions with compounding returns. When obligation forces you near the chronically unlucky, contain the exposure with fixed time, defined help, and no shared fate, so that their pattern never becomes your story.

What "infection: avoid the unhappy and unlucky" means, in one line: some people's misfortune is a pattern they bring with them, and if you stay close you end up living inside it. It is Law 10 in the book (it is sometimes misremembered as Law 11, which is about keeping people dependent on you). Greene's main example is Lola Montez, whose arrival at the Bavarian court in the 1840s helped bring down King Ludwig I. His point is not that she was unlucky once. It is that the same kind of trouble followed her from place to place, and each person who took her in shared the cost.

How to tell bad luck from a pattern. Everyone has bad years, and a friend who has lost a job, a partner or their health is not what the law is about. The signs Greene is pointing at are different: the same story repeats with new people in it, someone else is always to blame, and the people who help end up worse off than before. A useful test is to look backwards. If the last three rescuers of this person all walked away burned, you will probably be the fourth. In that case you can still help, but with limits you set in advance: fixed time, a defined favour, no money you cannot lose, and no sharing of their conflicts. These tests are ours, not the book's.

Where the law goes too far: read literally, it tells you to drop anyone who is struggling, which costs you the friendships that matter most and the reputation of being someone people can count on. It also ignores that luck changes, and that a person who is down now may be the one who helps you later. The fairer reading is about patterns and proximity, not about kindness. Greene adds the other side himself: good fortune and good humour spread too, so the company you choose shapes your own luck. The law follows Law 9, win through your actions, never through argument, and leads into Law 11, learn to keep people dependent on you. It sits in tension with Law 18, isolation is dangerous: choosing your company carefully is not the same as cutting yourself off.
