how to change your way of thinking by doing s.th. that's absurd
If you want to see the world different, you have to go out of your mental and behavioral comfort zone.
There are 5 interesting talks on TED.com about things that seem absurd. In my opinion they are not absurd but only uncommon to our normal approach in our life. In these 5 talks the speakers are talking about their experiences they have doing s.th. "unnormal". They got new insights, new answers, new ways of living. And I got some nice new neuronal connections in my brain which where not there before.
Try it on your own or view what the speakers are telling you about their approach. Watch some shared experiences of absurdity in public places (like wearing no pants in a subway train in winter), collect the secrets of people they haven't told to anyone before, try to live as healthy as possible (and find that it could be really unhealthy doing it in the extrem), or play a little game with the Encyclopaedia Britannica in the internet (and learn s.th. that your father doesn't know).
You can watch all of them by clicking in the vid above, or you can jump right to one of the talks by clicking on the according link in the list (you'll go to ted.com):
