Good salespeople will create trust by deliberately making promises and then keeping them. So for example, if a client requests some information, the salesperson will promise to send it by a certain time, say in ten minutes, and then send it, even if the information could have been provided immediately. The act of making the promise and delivering on it builds more trust than just responding to a request. I heard this on a video presentation awhile back. I've forgotten the source but the concept has stuck with me. Stephen Covey, author of Seven Habits for Highly Effective People, also points out that you can become a trustworthy person by making and keeping commitments, even if the commitments are to yourself. He suggests starting by making a commitment to yourself to rise at a certain hour tomorrow.
