There are so many. I think if you haven't met a Julius, chances are you are Julius..

I wonder, how does a Julius perceive another Julius, as another competent worker? What about a non-Julius then?

I've seen it rationalized by saying you should be moving jobs every year or so, because if you're not doing that, then you're not growing. I've always thought of this as a sort of Julius coping mechanism. On some level, I think a Julius views a non-Julius as a stagnant old gray beard who rejects the "growth mindset".

To be clear: I've never seen people who follow this strategy contribute anything of value, and it's the biggest red flag on a resume. You learn and grow more by seeing things through.
