A little ambition is healthy, but obsessing over a specific position or worse, coveting your coworker's job, can seriously hurt your career.

This kind of obsession can damage your relationship with not only the coworker whose job you are after, but other coworkers who might feel threatened by this behavior.

Even more important is the possibility that by focusing on a particular position you might miss out on other opportunities for advancement that might be even more advantageous.
