When I look around the world and see so many countries turning people away, I think it is terrible. And I know that these are all issues that Germany is culturally dealing with in terms of integration but it is just something that I deeply admire.

I think that people just have this core desire to express who they are. And I think that's always existed.

The companies that work are the ones that people really care about and have a vision for the world so do something you like.

People influence people. Nothing influences people more than a recommendation from a trusted friend. A trusted referral influences people more than the best broadcast message. A trusted referral is the Holy Grail of advertising.

So many businesses get worried about looking like they might make a mistake, they become afraid to take any risk.

In the olden times, privacy was good. Today people want to share, people are more open.

Don't discount yourself, no matter what you're doing. Everyone has a unique perspective that they can bring to the world.
