The Importance of Focusing on One Metric

I try to simplify things, kind of distill it down to the least common denominator. And I just focus obsessively on them. The more daily active users we have on our service, the more likely they are to come back time and time and time again. That means in turn, they're more likely to build better collections that they can share with their friends. My dumbest mistake is just taking on too much, doing too many things at the same time.
