If You Are Irreplaceable, You Will Never Be Promoted

Being the only person who can do your job feels like job security, but it is actually a career trap. When nobody can replace you, your manager cannot afford to move you up -- or anywhere else. True career growth requires making yourself replaceable in your current role. Document your processes, train your teammates, and build systems that run without you. This is not about making yourself disposable -- it is about proving you can build something that outlasts your direct involvement, which is exactly what higher-level roles require.
