Look for when the environment is changing - the big shift now is mobile Internet. It's really happening big-time. The way you interact with services on a smart phone compared to the Web is quite different, so there's a huge opportunity.

The next Google or Facebook will come from somewhere other than Silicon Valley.

We have just started, and if you compare the number of people using Skype to the number using a telephone network around the world, we're still just starting.

I hope that my investment into Atomico will become my best financial investment to date.

Another differentiator is that Skype is free and simple to set up, and it costs us virtually nothing for a new user to join the Skype network, which is why we can offer the service for free.

People need to access Skype wirelessly, no matter where they are, and what happens is that we'll be taking advantage of the rollout of Internet everywhere - WiFi and WiMax in particular.

If you want to be an entrepreneur, it's not a job, it's a lifestyle.
