Yes, but part of a balancing act.
Sole IT person so I have to schedule my days so there is room for “fun”. Sometime unexpected may happen. You will always have unknown unknowns.
So I try to leave a buffer, which may merely be letting my computer do some automated task that in theory could be time used for multitasking, so if a hiccup occurs my schedule can take the blow.
A schedule that is so full and so packed you can’t even spare a few moments to Reddit is one where a “fun” surprise may wreck. It is one where illness or needing a burn-out avoiding vacation may also wreck.
The goal is to balance tasks such as preventative maintenace, skill learning, skill upkeep, etc. With said buffer.
