Some of the formats of creativity conferences do not fit everyone. CPSI and some others are often seen as TOO RIGHT-BRAINED for some people. Some people who have read a great deal or have worked in highly creative fields do not always find the content of the workshops fit them.
One of the strengths of attending and becoming part of the respective groups: CPSI, ACA, Mindcamp, ACE, FCW, CREA has been connecting with others in the ever-growing creativity development field and developing many varied types of friendships across the US, Canada and around the world.
Since I have been attending such programs since 1976 often I do not always find the workshop sessions to be for me but I do find the connection with others and the in-between, before and after hour discussions and spontaneous sessions to be highly valuable.
After 30 years I have become somewhat jaded and critical.
Hope to some day cross paths face to face with you Peter.
Hope your enjoy and find Tim's book: THINK BETTER very valuable.
He and his colleagues at thinkX have developed some excellent systems and tools for idea generation from individual to group and problem finding to solution.
