“Nothing is easier than self-deceit. For what each man wishes, that he also believes to be true.” Demosthenes
Dishonesty is one of the worst characteristics a person may possess, and we tend not to socialise with people who we know to be liars, yet we constantly lie to ourselves. Usually we do this when we know that what we are doing is wrong and we try to justify it. That way we do not feel so bad about what we did or what we are doing. As the quote above states, it is really easy to lie to ourselves. We believe something to be true if it is what we want to be true.
To me, personally, I think the worst thing one can do is lie to oneself. We need to be honest and face the things we have done or are doing. That is the only way we can stop doing it and fix what we have done already. By continuing to lie to ourselves, we will only make things worse, and hurt ourselves and probably others even more.
We are the only people that really know ourselves, so while we might be able to hide things from others and fool other people; we can never do so with ourselves. Deep down we know when we lie to ourselves and we know what we need to do to fix things. The first step to be taken is to admit that you are lying to yourself. In the end, honesty is the best policy...
