Absolutely. No matter how gifted a person is, there is going to be some point in their lives or some domain where pure talent will be insufficient.
Even super geniuses like Terence Tao struggled (he nearly did not pass his generals).

The American Mathematical Society has a PDF of essays of brilliant mathematicians (including Terence Tao) who despite their abilities, faced obstacles and difficulties that their sheer talents were inadequate to overcome, and they had to persevere.

Two articles I wrote at the time which hold up surprisingly well:
https://blogs.ams.org/mathgradblog/2010/12/28/spaced-math-repetition/
https://blogs.ams.org/mathgradblog/2011/03/10/space-math-repetition-re…
And an example of some of my cards:

If I'm being honest, I went overboard. Like I said, I literally memorized entire books. Entering cards into the system was the most difficult part. But it absolutely works! Had I stayed in academia, I would have loved to developed a set of flash cards to go along with course material.

This poster presentation of non-Euclidean geometry is really one of the best demonstrations that I've ever seen of these ideas. The precision and clarity of the hand drawn figures is lovely.

I don't know about the ratios (or how a user looking through could really tell what the true ratio is) but as far as none of them having a decent matching algorithm... I'm a big fan of OkCupid here... (I know they were aquired by match but they still operate independently AFAIK) I interviewed for them 12-13 years ago but never worked there, but they were Harvard math guys who founded SparkNotes and "opensouced" an early version of their basic matching algorithm in 2004 or 2005 on their blog, I'll see if I can find and post here or perhaps someone else will share bit the gist was only using the intersection of questions you both answered, and both of you don't just answer the question but also give how much you care about the answer to this question and "acceptable" answers from your match (if you care at all, if not answers don't matter) and they use those to customize weight of each question in matching... I don't know if it has any special romantic matching qualities but it's WAY better than anything else I've tried for a metric of people worth meeting and who you'll sometimes have INCREDIBLE amount in common with, when match percentage is over 90 or 95%... I've dated two 96+% matches for over a year FWIW.
EDIT: couldn't find original blog post but this article seems to have some of the same math/details in less entertaining form

A similar question in math circles is which direction you eat your corn, across like a typewriter is thought to indicate algebraists, while vertically by rotating and eating in a spiral indicating analysts (analysisists?)

It helps to think of the things _around_ math rather than the elements of any particular mathematical field. For example, the authority conveyed when an economics argument relies heavily on partial differential equations. Those things _around_ math are studied in the anti-racist math classes.
The American Mathematical Society has been grappling with this:

Pure math is very different than social studies. But, in applied math, your research will be used for something promoting one group over another. Personally, I find it manipulative to attribute my own problem-solving contributions to the politics of someone using them.

Vector Calculus, Linear Algebra, and Differential Forms: A Unified Approach
It's a rigorous but chatty textbook in the style of Spivak but written by someone who is sensitive to applied maths. I would not have survived my astrophysics classes without it.
(Not to mention it's where I first saw this really intuitive way of doing matrix multiplication: https://blogs.ams.org/mathgradblog/2015/10/19/matrix-multiplication-ea…

"Statistically speaking, you are probably taking up room that should go to someone else. If you are a white cis man (meaning you identify as male and you were assigned male at birth) you almost certainly should resign from your position of power. That’s right, please quit. Too difficult? Well, as a first step, at least get off your hiring committee, your curriculum committee, and make sure you’re replaced by a woman of color or trans person."

I looked around and found this guide by MAA:
https://www.maa.org/programs-and-communities/curriculum%20resources/in… It's not specifically active learning, but has lots of good classroom tips.
I also found this blog post series: https://blogs.ams.org/matheducation/tag/active-learning-series-2015/

Wasn't this the guy that claimed to have some new proof on the Riemann hypothesis? What eventually happened? I'm not sufficiently into the mathematics field to stay engaged with this news but I'm curious to see what was the deal in the end. I remember lots of people being generally upset.

Some discussion already over here:

Interestingly I posted[0] a link to exactly this story[1] from a different source around 12 weeks ago - it sank without trace. I wonder if this will fare better ... it's an interesting problem.

Links that would've been nice in the article:
Craig Kaplan's page on near-miss Johnson solids https://isohedral.ca/a-new-near-miss/
Jim McNeill's polyhedra pages http://www.orchidpalms.com/polyhedra/ Near Misses page http://www.orchidpalms.com/polyhedra/acrohedra/nearmiss/nearmiss.htm
The article says "by Evelyn Lamb February 21, 2019"
..but at the bottom says "This article was originally published in our “The Absurd” issue in June, 2017."
..but John Baez's article "Rectified Truncated Icosahedron" (i.e. the name of Kaplan's solid) is dated April 1, 2016. https://blogs.ams.org/visualinsight/2016/04/01/rectified_truncated_ico… .. Lamb somehow omits the solid's name. Baez refers to Johnson, Kaplan, McNeill and a lot of other people/sites as well. And links to them! Both have blogged for the AMS.
Unless Lamb is Baez, this seems oddly like plagiarism. But I guess there must be some decent explanation.
edit: Although maybe that's ridiculous - the articles are different: she's got some quotes from each of the main players - even Baez - including tidbits about other near misses (Only the Simpsons-Fermat one was new to me, so they didn't seem the meat of the article).
