"The salesperson's most valuable, least renewable resource is time. Time spent on a bad opportunity is time stolen from a good one.""销售最宝贵、最不可再生的资源是时间。花在坏机会上的时间，是从好机会那里偷来的。"——业绩的差距常常不在成交率，而在你把时间押给了谁。— 顾问式销售通识（qualifying 的核心逻辑）
EN Your product copies infinitely; your time doesn't. Every hour on someone who'll never buy is an hour stolen from someone who will — that's opportunity cost. Worse is the sunk-cost trap: the longer you've chased, the harder you cling, pouring good time after bad. Qualifying step one is treating "should I chase this" as an investment call, not a faith that effort always pays off.
为什么有效 · 机制与证据
Why it works
机制：追错客户的亏损有两层——看不见的机会成本，加上让你上瘾的沉没成本。时间是零和的：这一小时给了 A 就给不了 B，但"没追 B 的损失"不像账单那样跳出来，人系统性地低估。而已投入的时间会反过来绑架你——大脑把"放手"当"承认亏损"，损失的心理权重约为等额获得的 2 倍（损失厌恶，前景理论），于是宁可继续砸钱也不认错。两股力合起来，让人把最多时间喂给最会拖的人。
"Budget, Authority, Need, Timeline — if you can't check these, you don't have a qualified opportunity, you have a conversation.""预算、权力、需求、时机——这四项打不了勾，你手里就不是一个合格机会，只是一次聊天。"— BANT 框架（源自 IBM，1960s，业界通用）
EN Don't allocate effort on a hunch — turn "promising" into checkable signals. Classic BANT: Budget (is there money), Authority (can the person you're talking to decide), Need (is the pain real), Timing (is it now). Four greens = go all in; missing budget or timing = nurture, don't push hard; the person has no say (no authority) = climb the chain. Separate "likes it" from "will buy."
"The moment you're willing to walk away, you stop being a salesperson they need to defend against — and start being an advisor they can trust.""当你敢于转身走开，你就不再是那个他们要提防的销售，而成了他们能信任的顾问。"— take-away / disqualifying 的核心逻辑（顾问式 & Sandler 传统）
EN The most counterintuitive move: when the signals genuinely don't fit, you say "I don't think this is right for you." It saves both sides' time and often raises trust — even makes them want it more. A seller willing to push you away clearly isn't just chasing the close, and people want what they might lose. Caveat: this only works when you truly mean it. Faked as a "hard-to-get" act, it's manipulation and eventually shows.
"Don't ask who could use your product. Ask who your best customers already are — then go find more of them.""别问谁'能用得上'你的产品。问你最好的客户已经是谁——然后去找更多这样的人。"— ICP / 理想客户画像通识
EN Don't qualify ad hoc — keep an Ideal Customer Profile (ICP) as a ruler. Counterintuitively, don't imagine "who might be interested"; pull up the customers you've already won who stayed and renewed, find what they share (industry, size, pain, trigger), and turn it into one checkable profile. Score two axes — fit × interest — and beware the "enthusiasm trap": high interest but low fit wastes the most time.
恰恰相反：客户越少、资源越紧，越挑不起浪费。大公司有一屋子销售可以广撒网，你只有你自己——把仅有的一周时间喂给永远不会买的人，对你是致命的。资格判定对小玩家不是奢侈，是生存。而且"客户少"往往是没聚焦的结果：当你说清"我只服务像 X 这样的人"，反而更容易被记住、被转介绍——泛泛的"谁都能做"没人替你传话。所以越小越要有 ICP。早期样本少可把资格线放宽去多试探，但"看清每个客户值不值得深投"这动作，一天都不能省。
