The ability to gain and keep trust is a vital factor in being able to influence others. Research has shown, time and time again, that trust is always a contributing factor in the ability to influence others. When a person trusts you, trust alone can cause them to accept your message. On the flip side, if people dont trust you, all the evidence, reasoning, facts, or figures in the world wont get them to budge.
Trust can be an ambiguous concept, but certain things are quite clear: You cant get others to trust you unless you trust yourself first. Your message will not be convincing to others unless its convincing to you. Whenever someone tries to influence us, we ask ourselves, Can I trust this person? Do I believe him? Is she really concerned about me? We are less likely to be influenced if we sense that the person is driven solely by self-interest. Never assume that people trust you.
Always show the world you are someone to be trusted, no matter what the circumstances are. You can gain and enhance trust by doing the following:
Keep your promises
Be reliable
Under-promise and over-deliver
Admit your failures and weaknesses
Use logic...
