"Just trust me."

It's a phrase we've heard more times than we can count, and yet holds barely any meaning at all. Why exactly do we trust certain people and not others? What can we do to make ourselves more trustworthy? Don't let such a deceivingly simple task fool you. Gaining trust is one of the hardest but most important things to do. Read on to figure out how best to go about it.

1. Say only things you mean

There is nothing worse than an empty promise, no matter how small. Whether it's a friend who always cancels on coffee dates--or a team member who always asks for extensions on big projects--doesn't matter so much as the fact that both are consistently unreliable. Incessantly unfulfilled commitments show a very unappealing character fault: the inability to take responsibility for one's actions.

If you are unsure of something, simply do not guarantee that you can take on the task. While emergencies do occur and are understandable, we must commit to only making plans we are certain we can or will fully follow through.

2. Always be you

A lack of honesty or genuine character can be one of the first reasons others lose trust in you. Although it's true that people often have multifaceted personalities, making a valid effort never to put on an act is something many of us forget to do. It's easy to adopt a certain manner of behavior with one friend, and a completely different persona with another.

However, when our friends see us shifting between one personality and another, they begin to wonder who we really are, and whether or not we're always being fully transparent with them. Even though it's completely natural to change when with different company, we should put thought into ensuring that we are--at the very least--being as honest with ourselves and others as possible.

3. Demonstrate passion for good causes

These days, it pays to care about things that matter. Employees and customers alike are beginning to discontinue support for companies--and their leaders--if their priorities are not in check. We've seen it happen time and again before our very eyes. We've watched companies experience major backlash--and declining sales--for their CEOs' poor ideals. We've experienced the plethora of picketing and protest directed towards a corporation that was not adequately environmentally conscious.

Having moral values and standing unwaveringly by them shows that you will always stand by what you believe in, without compromise, and can be a crucial step in convincing others to instill trust in you.
