But this is what I am saying. From my perspective, you are making the same point that I am.
West Texas A&M University writes that...
There is no record of Einstein flunking or ever getting low marks in math. Albert Einstein was an all-around good student with exceptional grades in math and science, according to the biography written by Albrecht Folsing. The statement that Einstein was a poor student is pure myth.
However, according to MacTutor...
Following the failing of the entrance exam to the ETH, Einstein attended secondary school at Aarau planning to use this route to enter the ETH in Zürich.
(Passing the examination would have allowed him to study for a diploma as an electrical engineer at the Eidgenössische Technische Hochschule in Zürich.)
And yet...
"Einstein contributed more than any other scientist to the modern vision of physical reality. His special and general theories of relativity are still regarded as the most satisfactory model of the large-scale universe that we have."
In Einstein's own words, in an essay written at Aarau:
If I were to have the good fortune to pass my examinations, I would go to Zürich. I would stay there for four years in order to study mathematics and physics. I imagine myself becoming a teacher in those branches of the natural sciences, choosing the theoretical part of them. Here are the reasons which lead me to this plan. Above all, it is my disposition for abstract and mathematical thought, and my lack of imagination and practical ability.
He eventually succeeded with his plan, graduating in 1900 as a teacher of mathematics and physics. He then earned a doctorate from the University of Zürich in 1905 for a thesis
On a new determination of molecular dimensions.
Einstein returned to Germany in 1914 and accepted a research position in the Prussian Academy of Sciences together with a chair (but no teaching duties) at the University of Berlin.
So then, it was
research that resulted in Einstein's putting forth a model of the universe that others would then rely on.
Similarly, according to investopedia, William O'Neill worked as a
stockbroker (not a student) at Hayden, Stone, & Company in Los Angeles. He
developed the first computerized securities database at William O'Neil Co. Inc., which he founded in 1963. He
created the CAN SLIM growth investment strategy.
In my eyes, both Einstein and O'Neill are examples of how "there's more to it than that." O'Neil got actual real-world experience in the field, not just academic instruction, and then did his own research. Einstein had a disposition for abstract and theoretical thought. In other words, he did not merely operate on what he learned in school. He did his own research.
Your examples only reinforce my personal belief that it will typically take more than simply "learning the basics" for most folks to excell in most fields. Even for little old me, who most certainly does NOT regard himself in the same light as Einstein or O'Neill, it was by doing my own research that I was led to what I "claim" to be a profitable Forex trading system, which I take the liberty to call Numerical Price Prediction.
