Everyone believes about himself to be a man of values. But, those who really believe and follow value system, sometimes find themselves in situations where values raise conflict.
I recently found two such values are: Loyalty and Being Truthful. For example, there is a person/group etc. who are wrong but you supported them because he is close to you or you belong to same group. You may be praised for being Loyal.
But if you are thinkful enough, you may aptly feel that you were wrong in doing so as you were not on the path of truth.
At least for me, being truthful is more important than being loyal. So, whenever you find yourself strangled with conflicting values, always use your conscience and not your emotional baggage.
