Make promises small enough to keep, then keep every one. That’s how people start trusting the big ones.

Trust is assembled out of completed small promises. Nobody can tell in advance whether you will deliver something large, so they read the record of little things you said you would do, and that record is the only evidence on offer. Over-promising feels generous in the moment and spends credit you have not got. Under-promising and delivering quietly builds it up.

Shrink your next three commitments to sizes you are certain of, then meet all three exactly. Say what you will do and when. Build a yes that always means yes, because that is what makes the bigger ask possible later.
