There is a set of years, maybe a decade where learning what to do and not to do is learned by spending too much time doing so.

Productivity is a relative thing. Ask folks who take a few days off from a keyboard and notice a boost in speed in typing and making more progress than they were.

The idea of having pushes to rest and recover can be normal.

But time away from the keyboard to think (or not) and be creative (or not) is as important as time at they keyboard to allow the brain to make new connections between everything it's working on.
