We navigate in an endless process of learning. In this way we usually take knowledge from a lot of exterior sources, dealing with various knowledges such as practice skills. Most of the projects do require the support of a range of people that may come from our field or not. Even if designers tend to become swiss knifes, the discipline also carries a more complex way. That is to say, it is in the interests of the projects to overcome our own limits or to find out ideas we obviously wouldn’t have got otherwise, and surprise ourselves.
