Morale is key in design

Morale is key in design. I’m surprised people don’t talk more about it. One of my first drawing teachers told me: if you’re bored when you’re drawing something, the drawing will look boring. For example, suppose you have to draw a building, and you decide to draw each brick individually. You can do this if you want, but if you get bored halfway through and start making the bricks mechanically instead of observing each one, the drawing will look worse than if you had merely suggested the bricks.

Building something by gradually refining a prototype is good for morale because it keeps you engaged.
