I am being too glib. But the sort of "focus broken, can't move forward" feeling is something I constantly have felt in many non-programming tasks. Granted this blocking is also due to the nebulous nature of those tasks vs, say, fixing a bug. Most bugs (not all!) at least have some sort of definitiveness to them.
The coddling I talk about is stuff like other staff members being told to "not bother the coders", something I've seen first and second hand. That, along with many programmer's (myself included) habit of generating endless excuses for why something is not happening and it being more or less accepted as a given. But as someone who struggles with this stuff, I also know that a large percentage of it is due to my own behavior! And changing that has improved things.
My post is combatative, but mainly because I really want people who read this stuff to introspect on their own behavior, and _improve_, instead of assuming that the task is impossible due to some intrinsicc nature of the work that is overestimated
Writing is a daunting task for me, but that has more to do with my own talents and experience than anything. Not implying anything about yours, just something to consider.
The issue is not that programmers need to focus, is that they need to focus on deep, complex work. At least a few of those other tasks you mention (don’t have much experience with sales copy, and in rather terrible with both sales and copy) do require focus but have smaller reasonable increments of progress.
Stop thinking about the workplace for a moment and think more broadly of tasks throughout the entire day. Some of those are more easily put down and returned to than others.
Some examples of tasks which require focus but interrupt well: formatting meeting notes into minutes, simple accounting (paying bills, reconciling a ledger). The main point with these are that the individual units of work are small, and don’t generally require a lot of mental preloading to begin/resume working on. So if I am interrupted it can be irritating but I don’t really lose much.
Programming generally involves a lot of mental state that needs to be preloaded, and the Subtask units are often not small. That’s all.
Regarding the insinuation that this “myth” is the result of coddling at the professional level: if this were true, then non-professionals would not discover this independently for themselves…
