If you’re always available, you’re also always interruptible. Guard a few hours like they’re locked.

Being reachable at every hour sounds generous, and mostly it means your attention belongs to whoever texts first. Nothing that needs a long stretch of thinking survives a phone that answers every twelve minutes. The real cost is not the interruption; it is the twenty minutes afterward spent finding your way back to where you were.

Block two hours this week and treat them like a shift you cannot skip. Phone in another room, door shut, one thing in front of you. Tell whoever needs to know when you will be back, then be back then.
