First of all, we all have our own values, goals, our own TRUTH. It is what we consider to be of paramount importance to our life. It is the 'big picture' that we are trying to attain, and the means by which we attain it.
Here goes the point: in your life, you should NEVER betray your TRUTH. And the worst act of TREACHERY is kicking your TRUTH to the curb and going with the flow. Simply letting your TRUTH slip your mind and acquiring somebody else's vision is the most treacherous atrocity a man can subject himself to.
