Your inner circle should have a guest list. Open doors get crowded fast.

Closeness takes time and attention, and you have a limited amount of both. Treat everyone as equally close and the people who actually turn up for you get the same slice as somebody you met last month. Being deliberate about it is not snobbery. It is the only way the people who matter get enough of you to feel it.

Think about who you would call at two in the morning, and who would call you. Put real time into those few this month. Let the wider group be what it is, which is good company rather than a lifeline.
