Being replaceable in work may not seem like a good thing. But I definitely think it can be. Those who disagree tend to think about replaceability in a negative sense. Who wants to think there is someone else out there that can do your job as well (or better) than you? A lot of this comes from a scarcity mindset: that there are only a set number of jobs and once they are taken that’s it. But new jobs are created all the time as long as there is a case that demands it.
