I agree completely with this article. Math and physics are hard. It requires a certain disposition to be willing to sit with a problem for minutes or hours and have faith that you will be able to find the solution. The fields are also littered with geniuses and people with significantly more talent than yourself. The gap between those who tried and those who were gifted was severe at my alma mater(USC). I remember being in an intermediate mechanics course with only physics majors when our professor asked us how long it took us to complete the homework sets. I was regularly spending 15-25 hours a week on them. Some of my classmates were completing the sets in 2-3 hours. What shocked me wasn't that there were students who could complete the assignments that quickly but that: 1) students were either taking 2-5 hours or 10+ hours to complete the assignment. It was very bimodal. 2) that the gap in efficiency between the best and worst students was almost 10x. In comparison my estimate of the gap in efficiency between the best and worst medical students is 1.5-2x at the most. No medical student can claim that they can accomplish in 2-5 hours what would take another medical student 15-25 hours to learn. In the end I made the choice to go in to medicine where I was consistently in the top 3% of my class. There were a handful of 'superheroes' in medicine but not many. Most of us started in the same place and where we ended up ranking in our class was a function of effort. It was a refreshingly level playing field in comparison to physics.
