Although I started learning Six Thinking Hats only in Feb 2010, I do feel I have some experiences now. I read several Prof. de Bono's books, read the CD materials, practiced with my children, and provided several training seminars to ~70 engineers and ~200 operators. But I found I could not enforce people to think, even to my children, which may end up with an opposite effect. The thinking process is not really an attractive process for the younger generation when comparing to playing a video game.
I also encountered several people in Hong Kong that were officially trained in Six Thinking Hats classes, but I did not find they are practicing it. They just treated this as one of their knowledge.
When they use Six Thinking Hats, they found they need to spend some more time but they did not realize the benefits (although I did find some improvements). I found I lack something to motivate people to treat thinking as an important part of life so that they can put effort to improve them.
I start this thread with the target to get some real examples. How life was changed after practicing Six Thinking Hats? These may be good stories to tell during classes and to talk to people for motivating people to spend more effort.
