There's a natural resistance to keeping rules. It's part of the human experience. Although we want people to obey our rules, we resist their rules on us. Designers are no different. We might even be worse.
Our desire to be creative can drive us to stretch or ignore the rules of design, or the client's wishes. However, the goal of good design does not require breaking rules.
Understanding and using the rules (or principles) of design can actually empower our creativity. It makes our designs effective. And, paradoxically, they inform us when we may need to break a rule or two, when we fully understand the rules.
And there's the rub. To break design rules, we must do more than know what they are. We must understand why they became rules in the first place. As G. K. Chesterton once said, “Don't ever take a fence down until you know the reason it was put up.”
In other words, rules are not made to be broken. They are made to guide and inform us.
