Never exhibit a "holier than thou" attitude
Among some of the most negative human behaviour is the one that is called the "holier than thou" attitude. It is simple. I make a mistake. Someone else in the same department also makes a bigger mistake but when confronted, I try to make out a case that he had done a worse mistake than me.It is wise, for example, to never poke one's nose into the personal affairs of another colleague. When we start a gossip game, someone else will blow it up. When it reaches serious proportions it can hit us hard. The best alternative is to be totally aloof and stay far above such nasty games. Similarly, when we are absolutely honest about use of company money, this "hoiler than thou" game will not even be applicable.
Such examples abound. It is wise to stay clear of any controversy. Sincerity, honesty and integrity is always appreciated. Let us make a note of this at any point in time.
