The holy trinity: Usable, useful and desirable experiences.
“There is no justification for designing something that doesn’t solve a problem. However, the whole world is ready to consume things based on their aesthetic elegance. We cannot ignore the value of beauty. So, as a designer, if you can use your problem-solving ability to create a product that has great utility—as well as characteristics such as desirability, elegance, and beauty—and inspires pride of ownership, you can create a delightful ownership experience. Human emotions such as joy, pride, and love will enrich your product experience and actually give life to the product, making its ownership compelling and truly fulfilling.”
