Establishing integrity and never wavering from it supports everything you do through good and bad times. People may not agree with you all the time — or you may not be right all the time — but they always will know that they were getting it straight and honest.
Integrity helps to build better relationships with customers, suppliers, analysts, competitors, governments, and most important of all, friends. It sets the tone in your business / organization.
Never have two agendas. There is only one way — the straight way.
