Notice who you want to text first when something good happens. That’s your real circle.

The instinct to tell someone is unguarded, which is exactly why it is accurate. Before any thought about who ought to be told, your mind has already chosen, and that choice shows who you trust with good news, a harder test than it sounds. Some people are difficult to tell good things to. Your reflex has already taken that into account.

Notice the first two or three names next time something goes well. Then check whether your calendar matches the list. Most people spend far more hours with those who were not on it.
