You know you are very comfortable with where you are in life when you've not only mastered the art of public speaking, but when you can break out into a song to conclude your presentation. Venture Capital legend Tim Draper opened Radio Ink's Convergence with a presentation on viral marketing, how he helped Hotmail explode to success, and how he looks for people and companies that break down big barriers.
Examples he cited included Skype breaking down the telephone, e-Bay breaking down the barriers of trade, and Facebook creating the new neighborhood. He concluded his presentation by singing a song he wrote. You can watch the video of that song here.
