Most people prefer to do business with a person they trust. Trust is a very fragile quality that takes a long time to develop yet can be destroyed in a moment. Integrity is another important virtue of trust.
Integrity is defined as having an upright and complete character.
Found at the core of all of us is intrinsic goodness. Integrity emerges when we live from that place of goodness. If so, then you are probably acting with integrity. You'll start to build more trust and commitment.
