Trust

"Your reputation and integrity are everything. Follow through on what you say you’re going to do. Your credibility can only be built over time, and it is built from the history of your words and actions" - Maria Razumich-Zec

You do not need a lot of people around you to make this a true statement. Even a stranger to you can attest to this if they experience your good word, backed up with its strong action. 

People need people they can rely on and trust.
