I like some of this interview with Irene Au, Director of User Experience at Google.
I think it’s really important to be very pragmatic about what you’re building, and how quickly you’re building [it]. There’s a balance [that must be struck when pursuing] something that’s really perfect. When you’re innovating very rapidly, sometimes you just don’t even know how things will be used and what [they’ll] be used for. So sometimes it’s just important to get it out there. Being able to adapt to the conditions and the environment…that was kind of a survival skill that I had to learn.
