I used to do a very niche job (that does not exist anymore) that required great skill, and I was so good at it, I was likely in the top 10 of all time. There were less than 1000 people qualified to do this job, and I was in the top 1%, AND those ~1000 people were the only ones to ever do this specific job out of the ~8 billion people on this planet.

Now I work a relatively mundane IT job, and no one knows or cares about what I have accomplished, except for my peers.
