The short answer
Knowledge doesn't scale just by being shared out loud. It sticks when the people receiving it can absorb it, practice it, and pass it on themselves. Your job isn't to broadcast — it's to build the conditions where others can own what you know.
You keep sharing, but it isn't sticking. Research on knowledge transfer shows why: what you know is partly tacit — embedded in how you think and move, not just what you say. The people around you also need the right foundation to absorb it. Without that, your sharing stays surface-level. It reaches ears, not hands.
Marcus put it plainly: maintain your purpose free from compulsion. Your purpose here isn't just to speak — it's to make the knowledge live beyond you. That means shifting from telling to embedding. Stop measuring success by how clearly you explained something. Measure it by whether the other person can do it, teach it, or improve on it without you.
This week, pick one thing you know well and teach it to one person — not by explaining it, but by having them do it while you watch. Then ask them to explain it back to you in their own words. That loop — do, reflect, teach — is how tacit knowledge moves from one person to another. Do that once. Then build the habit.
