And mine as well, and anecdotal for sure. But, if there's something to it, I'm not sure how to account for it. Though one thing comes to mind.

Some time ago, a study was performed in my home country to look into possible correlations between academic performance and work performance among doctors. As it turned out, the best performing doctors were not those with top grades, at least not before entering medical school.

Those who did best had left high school with adequate grades, but not good enough to get into medical school. Rather, they had spent time and effort with supplementary studies to get their grades up to the level where they could apply for medical school.

The possible explanation that was presented was that some of those who had great grades straight out of school simply chose to become doctors because of the promise of prestige and remuneration. Those who didn't, but still fought their way into medical school, however, had a calling beyond money and status.
