What does it mean that input curation?

Deliberately choose your information sources rather than accepting whatever arrives.

Example: You open your phone in the morning and scroll through a feed of outrage, celebrity gossip, product announcements, memes, a friend's vacation photos, a thread about geopolitics you don't understand, and an ad for shoes. Forty minutes pass. You've consumed thousands of words and dozens of images, but you can't name a single thing you learned that helps you think better, decide better, or build something that matters. Now imagine a different morning: you open an RSS reader with twelve sources you selected because they consistently produce insight relevant to your actual work and thinking. You read three articles in twenty minutes, capture two ideas, and close the app. Same time budget, radically different input quality. The difference is not discipline. The difference is curation.

Try this: Conduct an input audit. Open your phone's screen time data, your email inbox, your browser history, and your social media follows. List every recurring information source: every app, newsletter, podcast, YouTube channel, news site, social account, Slack workspace, and group chat that regularly delivers information to you. For each one, answer three questions: (1) Did I deliberately choose this, or did it accumulate? (2) In the last 30 days, has it produced a single insight I acted on? (3) If I removed it today, what specifically would I lose? Any source that fails all three questions gets unsubscribed, unfollowed, or deleted today. Any source that passes all three gets promoted to your curated input list. Everything in between gets a 30-day probation — if it doesn't prove its value, it goes.
