Sounds like they're describing ADHD.
(Side note after the important ADHD joke: there's an old sport textbook called "Periodization" that mentions focusing on breadth rather than depth of sports experience in early life is a better path to olympic-level performance than just going hard in a single sport from a young age.)
ADHD is not correlated with high career performance, sadly, and represents a real obstacle for those struggling with it. The current social media trend of equating ADHD to a superpower which propels people to focus intensely and excel is really unfortunate.
Those who face this issue can of course try to "gamify" their upcoming tasks to themselves in a way that will hopefully steer that focus in desirable directions, but that's not always easy. The monkey mind also resists ongoing habit formation, which is the tool most non-ADHD folks would generally resort to in order to effectively manage their overall schedule and just be more on-task.
I was responding to the comment that compared the high performing people in this article to a case of ADHD.
I agree that the features of ADHD are not consistent with intense, directed focus on specific goals as discussed in the article.
