About a week ago, I was in Warsaw, Poland to give my first talk at a big conference, Front Trends 2010. As every first-time speaker, I was extremely nervous and worried that everything would go bad. That my talk would be boring or too basic or that I would just freeze at stage, unable to say a word. It was a 2-hour talk with a break in between, so I was also terrified that nobody would show up the second hour.
