 So, Greg, when somebody approaches you and says, I want to become a better service designer, what is the most important tip you can give them? So, again, to go back to what we discussed earlier, I think I always go back to self-skillers. This is about being a good listener, having a good empathy. Some people are just born with it. There are going to be some great people who have the natural skills of being able to sit down and listen, and ingest the information, and being able to sort it out, understand what was said to them, and be able to kind of like... And then the secret is to actually just turn this insight into something tangible, like the prototyping and the ideation part of it, to me it's key. So, every time I hire people, I really hire them based on how well they can understand, how well they can listen, how well they can turn a data point into a solution, into a solution to something tangible versus being... I don't even care if it's like Legos versus whatever it is, but I think it's very important for us to turn an insight into a tangible thing that people can understand and eventually buy.
