This document breaks 16 common design rules, encouraging designers to follow their instincts rather than strict rules. Some key points made include: forget who you are designing for and the design brief; go as fancy as you like rather than keeping designs simple; use colors freely rather than sticking to a theme; use multiple typefaces to convey different emotions rather than limiting to two; great designs are great regardless of being flat; and focus on standing out rather than being uniquely different. The document advocates breaking rules and conventions to create fresh, instinct-driven designs.
