This story was told by my lecturer, Abdus during his statics class. Enlightening.
There was a building, a kinda tall building. People there need to use the lift to go up stairs, upper floor, go down, this and that. However, they were complaining the lift is moving too slow...They are inpatient.
One day, they decided to hired the best engineers in the region to modify the lift into a super fast moving lift so people can go up and down fast and easily.
Engineer one: we could make a double decker lift which reach two floors at the same time.
Engineer two: we use better engine to pull the cable faster...
Bla bla bla.....
Lastly, one humble engineer says: all of you all designs and ideas is too technical and cost alot of money. People just do not what to do if they got nothing to do. They wanna kept busy. That why they are inpatient. How about we put mirror nearby the lift entrance of each floor..
Soon, problem solved. People no more complaining and some of even says that lift is coming faster that expected. They make themselves look nicely, comb their hair, put some make up, posting, adjusting ties or attire, tieing shoelaces while waiting for the lift.
Hence, an engineer is not only solve mathematical problems, its not neccesary to put equations, theory of so and so. Open your mind, be observative and you will get the key of the problem and solve it with cost effective way.
