In my opinion author fails to make distinction between small tasks (atomic tasks) and complicated tasks. Also misses to mention 2 important concepts: flow state and friction.

For small tasks you should absolutely strive to remove any friction (examples: editor undo, dictionary lookup, make a note).

Complicated tasks (writing a blog post) are a different beast: - needs to be broken down in small tasks - while carving out small tasks needs finesse and fluency - small tasks need to be frictionless

But, principal difference is you need to load your working memory (small but fast (RAM)) (e.g. read documentation, browse a repo, connect to your work from yesterday, ...). Loading your 'RAM' is an investment. And your ROI shrinks if you need to collect the threads from scratch again and again. So, IMO it's not about moving fast but moving uninterrupted. Moving uninterrupted produces flow state and gives you the impression of moving fast (despite your moving only slowly but steadily). Speed becomes irrelevant if you're moving steadily forward.

The blog post shows another problem if your working 'too long' on something: you need to reconnect from scratch to your original idea/intention, which might change. So your creation may become an incoherent medley, you begin to miss the forest for the trees, or worse: you begin to doubt yourself.

I like to think about the mind as an extensible limb that can extend in the direction of a distant goal, but can only span small distances. It's literally like the mind walking. Making steps too big is like moving trying not to touch the floor. It needs unreasonably more effort and is long-term exhausting. You may even break down and think you're a failure. But standing on one leg for too long is exhausting too.

You may laugh about the author who had this post 6 years in the making, but it's extremely important to work by a mental model that doesn't exhaust you, but works FOR you.
