The best leaders create replacements, not dependencies.

Building a replacement feels like working against your own position, which is why so few people do it. But dependence is a ceiling, since you cannot move on from anything nobody else can hold. Creating people who could do your job is what makes you promotable rather than stuck.

Name one person who could take over a significant part of what you do. Start handing it over in pieces this quarter, including the parts you enjoy. Do it before there is any pressure to.
