In the drafting-room the work of harmonizing must go on; compromises must be made between the ideal scheme of the dreamer and the requirements of the manufacturing and selling departments.

Next to the noble knight of the eraser comes the idealist who has been toughened by experience in the cold world.

The idealist aims to design and construct a perfect machine.  He is encouraged in his work by seeing a little clearer each day, month, and year of the time spent in the right kind of application to his work.  He knows that the work of last year is faulty, that this year’s work seems nearly perfect, excepting for a certain slight change that has just entered his mind.  He cannot think of allowing any machine to be made without this later improvement.

He is inclined to the optimistic view, his memory works best on the good work of the past, and is extremely poor in holding afresh the view of previous mistakes.
