Follow through until trust becomes efficient.

Early in a relationship, everything has to be verified, negotiated, and confirmed. After enough follow-through, all of that overhead drops away and things happen with a fraction of the effort. Trust is not just pleasant. It is a substantial reduction in the cost of working together.

With someone new, over-deliver on the small early commitments. The efficiency you buy in the second year is worth much more than the effort it costs in the first.
