I love these anecdotes. The only way to disagree with these is to tell the OP that they are too talented and skilled and that the average person wouldn’t make it in their shoes.
According to IQ tests I am literally mentally “retarded” and my SAT scores were in the lowest percentiles. I honestly have no idea how I got a BS degree and have worked in tech for over a decade. But if my dumb ass can do it, so can others.
