I agree that practice can be tremendously valuable in knowledge work, but at some point in the skill curve, once you have built up a the ability to accurately self-evaluate the value of practice goes down because the work itself is the practice. Benjamin Franklin was referenced in the article, and there are far more examples in his life than just the writing exercises where he employed deliberate practice to improve his ability in an area. But he didn't continue these once we was rocking these skills at a world class skill level - instead he switched to practicing new skills he wanted to add. But if you haven't tried doing so deliberate practice - I'd highly recommend it.
