The word "genius" is one of the most misused terms in history.
While it's often referenced accurately, the connotation that we commonly associate with it diverges away from the truth.
We correctly label intellectual brilliance and creative power as genius — and we should — but it's about time we stopped assuming that those things arise from talent or inborn giftedness alone.
In fact, more and more research is showing that while talent is indeed responsible for some extraordinary results, most accomplishments generally result from a combination of practice, habit, and mindset.
Van Gogh was a genius. Mozart was a genius. Marie Curie was a genius.
That said, basing those assertions on their natural talent is not only plain wrong, but it also cheapens the daily work and effort that it took for whatever talent they did or didn't have to manifest to the degree that it did.
Genius is naturally context-dependent, and it takes more than just the few steps that any article on the internet is likely to highlight, but general intelligence and creativity can be improved pretty easily by anyone.
In fact, all it really takes is an hour a day.
