Around five years ago there was a thread about books that changed your lives. Someone wrote about Impro by Keith Johnstone - an introduction to improvisational theater interspersed with a lot of personal stories. I read it and fell in love with the honesty and the new view of social interaction the book offered.
I found a dance theater studio near me - the closest thing to impro theater that was available - and went there. It was there that I met some of my most important friends and developed practices that I use to this day in my artistic projects as well as in interaction design.
