busy people usually are flexible people, they adjust well with situations so to accomplish their tasks. This is good, what is not good is how some of these people are changing their positions very quickly to match their different circumstances.
My boss is one of these busy successful people, he is good, except that he really changes his positions very often. One day he says something the other day that thing is not necessary. When i ask him something he answer so and in front of other people he says something else. He is not a liar, he only adjusts himself as to whatever is more suitable for him. And while this is not serious thing, its frequent happening is disappointing.
