It's finally there, the TEDx Wroclaw speech about zest riddle I gave in March 2013 is finally up and available online for all to view. Yes, it was quite a challenge to open the whole conference with my speech (well, the proper title for this talk should go something like this: Karol Liver on how to develop Darth Vader voice to survive a TEDx talk at 8am after 3 hours of sleep), but also an extremely rewarding experience for at least few great reasons: to confront yourself with a stage fright and talk in front of enormous audience of 300 in a large cinema room with a gigantic cinema screen to project your little slides on, to stay cool being blissfully aware of the whole thing being recorded and live-streamed and finally, to attract people to my experience of designing and maintaining zest through all those years. But the challenge was accepted!
