Once you see that an answer is not serving its question properly anymore, it should be tossed away. It's just their natural life cycle.
They usually kick and scream, raising one hell of a ruckus when we ask them to leave. Especially when they have been with us for a long time.
You see, too many actions have been based on those answers. Too much work and energy invested on them. They feel so important, so full of themselves. They will answer to no one. Not even to their initial question!
The hardest thing about customer interviews is knowing where to dig. An effective interview is more like a friendly interrogation. We don’t want to learn what customers think about the product, or what they like or dislike — we want to know what happened and how they chose...

No matter what you love to create, there is something to be learned from the way Hans Zimmer approached the Dune score. We are all striving to create work that is novel, innovative, memorable, and inspiring. To get there, however, we tend to focus on getting things right, on avoiding mistakes, on “being professional”. Yes, it is important to have the commitment, dedication, and attention to detail of a professional. But being right? That will only take you so far. What is much more important is to approach the problem in front of you with curiosity and an open mind. With an urge to explore what can be found beyond the ordinary, beyond the right way of doing things. If you want to create something that nobody has come up with yet, it is important that you try out all the crazy ideas others are afraid to try, that you build prototypes, improvise, and freely play with the materials and the technologies you have at hand.
