 Marie, so when people approach you, it could be students, it can be anyone from business and ask you, I want to become a better service designer, right? What is the ultimate tip you give them? I guess the ultimate tip I would give, and I gave this tip to my students and everyone that approached me asking how to become a better service designer. I always say be comfortable or learn to drive value from ambiguity. Don't try to put things on a straight jacket. There are ways to drive value and create a lot of value and especially co-create value by acknowledging and playing or dancing the dance of ambiguity. There's a huge bucket of value to be tapped around avoiding reducing things to a cake recipe.
