Amir Klein (PM at monday.com) argues that the PM job is collapsing under the weight of context. Every initiative requires you to assemble fragments from Slack, Notion, decks, dashboards, CSVs, customer interviews, and your own memory of what's already been decided. Klein's metaphor: you're carrying a giant basket of eggs, watermelons, and toy cars, and you're on the move. The synthesis is the job — but doing the synthesis in your head, over and over, is what burns you out.
His answer is a second brain: a ChatGPT (or Claude, or Gemini) Project that you build around one initiative, fed with everything that lives in your head and in your tabs. Crucially, Klein insists the second brain doesn't dull your role — it sharpens it. Reasoning, product sense, taste, and judgment stay yours. The Project just clears the path from your insight to the output.
Klein's workflow has three steps. First, define the personality of the Project — explicitly ask it to push back, challenge weak ideas, and not always agree. Second, dump every artifact you can — and his "whoa" moment is realizing that everything is essentially text: decks become PDFs, dashboards become PDFs, Slack channels become PDFs. Third, let it cook: lean on it for sign-up form copy, Lovable prototype prompts, and — most powerfully — tailored communications (the marketing blurb, the QBR sentence, the sales enablement deck, the user-testing script). The reload cost between audiences is what eats half your day; the second brain eliminates that cost while leaving the calls in your hands.
The living-thing piece matters: feed the artifacts you create back into the Project so it stays current. Treat it as a companion that grows with you, not a one-time setup.
