Do Not Become the Only Person Who Knows How Something Works

Being the sole keeper of critical knowledge feels powerful, but it chains you to a specific task, team, or project. You cannot take a vacation without anxiety, you become a bottleneck for your entire team, and any career move means abandoning institutional knowledge that disappears with you. Share what you know systematically. Write documentation, pair with colleagues, create runbooks, and cross-train your team. The goal is not to hoard expertise but to multiply it. People who spread knowledge freely are seen as leaders, not as interchangeable parts.
