there is a common thinking within the working environment. Although logic will tell us to do the right thing. But many a times, we only want to do things not wrong. Not right, but no one can fault us still. This is call PLAY SAFE.
The best way to play it safe is to continue to do the things that others have done before. Often resulted in no break through.
No break through = no outstanding result = no visibility = no fame = no recognition = no promotion = no pay increment
Remember, every task that you are doing is an opportunity to shine in itself. Next time, when you are in charge of a project, ask yourself, do you want to be right or just be not wrong?
