You read it wrong then.

> affords me more time to relax, review what I have created, and enjoy it rather than drag myself to the next task

This is exactly what the author is promoting. A hypothetical so-called "worker bee" would indeed be moving on to the next task at the fastest possible clip.

It also says

> You should try and spend your time in ways that will benefit you and your employer.

Which is hardly antagonizing their boss, or slacking.

Depends on your definition of high performer.

If you prize delivering short-term value by chugging through the task pile faster than other people can, then sure this article is not aligned with your ideals.

That is not what I would call high performance; I would much rather be someone who can take a razor/lawnmower to that pile of tasks and do exactly the subset (down to potentially none at all) which delivers the most marginal value for the units of time I think are warranted for the project as a whole - then repeat until the goals are met.

Sometimes I want to stop and smell the roses, but mostly I want to smell the roses along the way while accomplishing other things too.
