> My class valedictorian went on to become a doctor and while that is certainly impressive to me, there are many doctors and he practices (like almost every other doctor) and isn’t pushing the boundaries of medical science.

You seem like someone who thinks things through, so I suspect you’ll know what I’m about to say, but given the sentiment of your comment, I think it’s worth explicitly sharing this:

The fact that your class valedictorian went on to be a doctor is great. Not everyone needs to push the boundaries. Your classmate may end up saving/helping countless lives.
