Fame
Let's see...famous pathologists...hmm...
How about J. Robin Warren? Doesn't ring a bell? He won the 2005 Nobel Prize in disease transmission for his discovery of the bacterium Helicobacter pylori. That's a huge deal, right? Of course it is. But the truth is the general public hears the term "bacterium Helicobacter pylori" and probably thinks it sounds more like one of Harry Potter's spells than anything else.
Our point is even if you climb to the highest ranks of pathology stardom, you're not going to be Kanye-level famous. However, there's the slim chance that you'll be a superstar in the scientific community. More than likely, you'll put in your fifty or so hours a week and nobody other than your co-workers, family, and friends will know much about you.
If you want worldwide superstardom, maybe try something else.
