Onur Cobanli explains:
Do you know how a pearl is formed? It starts with an irritation. Likewise, good design starts with an irritation, an unsatisfactory feeling for existing products and services, which leads to a designer thinking, thinking, thinking, working, working, working, doing, doing, doing and finally, after many cycles of thinking, working and doing, coming out with a product that serves as a cure to the irritation. Good design is never easy but it is always worth doing, it is satisfying.
