What does it mean that curate your information diet?

Deliberately choosing what information you consume is as important as choosing what food you eat — because your inputs shape the quality of every thought you produce.

Example: You check Twitter, Hacker News, three Slack workspaces, two newsletters, a Reddit thread, and a news app — all before 9 AM. By the time you sit down to do actual work, you've consumed 12,000 words written by other people and produced zero of your own. Your head is full. Your judgment is clouded. You couldn't tell someone what the single most important thing you learned that morning was. Now compare: a colleague subscribes to four RSS feeds, one industry newsletter, and one long-form publication. She reads for 25 minutes over coffee, captures two ideas into her notes, and starts writing. Same profession. Radically different epistemic clarity.

Try this: Audit your information inputs for one full day. Every time you consume content — a news article, a social media scroll session, a podcast, a Slack thread, a newsletter — log the source and an honest estimate of the time spent. At the end of the day, sort the list into three columns: (1) sources that directly helped you think, decide, or create, (2) sources that were mildly interesting but changed nothing, and (3) sources you consumed on autopilot. Be ruthless. The ratio between column 1 and columns 2+3 is your information diet's signal-to-noise ratio.
