Are there advantages to job-hopping?

Until now I've never sit in the same position for a year. My maximum time in a company was 11 months. So that point about always changing jobs and always looking what's there, it really hit me because that's what I did. When I moved to London, I was like... Every time I was looking for a new challenge. I was looking for working with smarter and smarter people. And I was looking to learn as many things as I can. And as soon as you start getting comfortable, you start looking outside for something more.
