A lot of people fucking hate having to switch jobs. This has little to do with their skills and a lot to do with all the stress and uncertainty that comes a major life change.
Some people enjoy making big changes and shaking themselves up, and that's fine too, but don't confuse that with some sort of inherent superiority.
5 factor personality model, one of the factors is "neuroticism" (the others being openness, conscientiousness, extroversion, and agreeableness; the mnemonic OCEAN)
neuroticism measures "the tendency toward negative emotion". Stress in the face of uncertainty is a good example of a negative emotion that can be exaggerated in some people. Negative emotions also correlate to less success in social and job situations.
This seems like a lot of justification to say that people who enjoy changing jobs frequently are objectively better than people who don't. I'm guessing you're in that first group?
