How do I keep my own life separate from the executive I support?

You solve the puzzle every day. Their calendar runs because you run it, and you are good enough that it looks effortless. But somewhere in doing it so completely, the line blurred. Their priorities became your priorities, their urgency your urgency, and your own life got quietly folded into theirs. That loss is real, and it is worth taking seriously. The skill that makes you great at this is also what erased the line: you took on their world as if it were yours. But their calendar is not your life, no matter how fully you hold it. You are allowed to serve well and still keep a self that is not on their schedule. The devotion does not require your whole existence. Draw one line and defend it. Pick a block of your own time, an evening, a morning, a weekend, and protect it as fiercely as you protect their most important meeting. Start small but hold it firmly. Rebuilding where you end and they begin starts with one piece of time that is only yours.
