I am abundance.

Some people function as a kind of exchange. They know who has a van and who is moving on Saturday. They introduce two strangers and then forget about it. Nothing is being managed; they simply carry more of other people's situations in their head than most of us do.

It costs very little and it changes what flows past you, because a person who circulates things becomes a place things get sent. Being generous with information is the cheapest version of this, and almost nobody does it on purpose.
