A woman in hot air balloon realized she is lost... She reduced altitude & shouted to a man below: Excuse me, can you help me? I promised a friend to meet him an hour ago but I don't know where I am. Man below replied: You are in hot air balloon 30 feet above the ground. You are at 41 degree North latitude & 59 degree West longitude. Lady: Oh, You must be an engineer. Man: Yes! How did you know? Lady: Everything you told me is technically correct but useless & the fact is, I'm still lost. Engineer: I see, then you must be in Upper Management. Lady: Yes! How did you know? Engineer: You don't know where you are or where you are going. You made a promise, which you have no idea how to keep & you expect people beneath you to solve your problems..!!
