Doing what client wants with GDD. I mean x = y

Not listen to other people is a GDD way of life. Everyone think that they can do something by himself. It's natural to think but it's even more natural to behave like you want and not listen to other people. Imagine the situation: you demand someone to go on a trip by train. The person goes by car. That's the problem is x = y ? Now think as the other one. You wanted to go by car because you wanted to take your family. Why didn't you do what was demanded ? You want to think on your own. People who demands things mostly knows what problems could happen. Now the car got broken because of the maintenance and figure out who is going to be mad ? Both people. So now the when someone ask you to do something on his way just do it. Don't waste your brain thinking in a good way or you can be as you are now a GDD follower.
