The biggest barrier to starting a company isn't ideas, funding or experiences. It's excuses.

I did interviews with most of the TechCrunch50 experts backstage and there was a common gripe about the companies launching there: Not enough passion, not enough swinging for the fences, not enough trying to change the world... One big exception was CitySourced - a company that excited Kevin Rose precisely because it was trying to build something that doesn't really exist today and would make a huge difference in people's lives. It was the most excited I saw an expert about anything over the two-day event.

If Mark Zuckerberg doesn’t understand something, it’s not defeat. It’s not even something he has to accept. It’s merely a challenge he needs to engineer his way out of, and that includes human emotions and relationships.

Stop looking at the Web as merely a display opportunity and not a way to interact. That does not create a new business model, it just shifts one that isn't growing and is outdated. The reason sites like Google are stealing advertisers from daily newspapers is not because Google has more eyeballs. It's because Google used the interactivity of the Web to deliver a new, better way to advertise.
