Many people are having trust issues. They find it hard to believe that people can be trustworthy and of a high integrity. They think everyone wants to cheat them or take advantage of them. They always think that no matter how good a person may appear to be, the person must have a hidden agenda or ulterior motive. Now why do they have such a mindset about everyone? Usually, it is claimed to be based on their experiences.
Why is this kind of thinking dangerous? It makes one see everybody as an enemy and a potential carrier of malicious intent therefore one always looks out for the negative things neglecting the sincerest effort of goodwill that may be directed to him/her and once such people see something that finally looks like a negative thing, they'd be like "Aha" "I said it, He/She is as evil/bad as I had thought ".
Now here's the thing about TRUST. Some people have attached so much value to trust that once the person whom they trusted somehow disappoints, they find it very hard to ever trust anyone else again. By putting themselves in this position, they shut out every single person as being untrustworthy. Ultimately, a sincere person coming around such people will always be seen by them as untrustworthy. And one thing with our mind is that whatever it wants to see in something, it has a way of seeing it. If you see everyone in the world as "bad", no matter how good they are, you must point out something bad about them which only you may be seeing.
To try and advice those having trust issues, I have something to say. To TRUST someone does NOT mean that the person cannot ERR. It does not mean that that person cannot do wrong. Every human being has the potential to do either good or bad. The potential is always there. Those who claim they cannot ERR are only deceiving themselves. Wise men and people of integrity understand that they have this potential in them, but they strive to do good. It doesn't mean that in striving to do good one MUST never fall. No!
Understand that the probability of falling in every man is always there. Someone making a mistake should not be so shocking to us because we ourselves are not even perfect and as consistent as we want to be.
I believe it is best to give everyone the benefit of doubt. Those having trust issues close their minds completely against everyone because they generalize the outcome of their experience to be what every other experience leads to. That Mr. A is a bloody liar does NOT mean that Mr.B is also a liar neither does it mean Mr. A can never change at some point.
We must make room in our minds to experience people for who they really are and not assume/guess what kind of people they are.
No one is perfect. This doesn't mean we shouldn't strive for perfection.. at all times, we must. But by trusting someone, let us not see it that the person is already perfect. We have to make room to accommodate some faults in some people and correct them with love. That good people make mistakes sometimes does not make them evil people. In our disappointments with people we claim to trust, let us understand that these people are still human beings that could still err, not angels. If you have made a mistake yourself, why should you think someone else CANNOT make a mistake because of your TRUST in them?
Understand the nature of human beings and try not to judge another human being based on previous experiences you've had. Keep and open mind and experience people for who they are not the opinions you form about them. Also get the point that everyone is still striving for perfection and no one is already perfect.
