If people are passionate about your product, whether it's because they're hating or loving it, those are both good scenarios.

We focus a lot on culture specifically at Twitter because of this spotlight, and of the fact that we don't want to end up like the child actor who found success early and grew up all weird and freaky.

Once true passion hits you, you can recognize all the times in your life you were chasing the wrong dream. And after you've experienced that sustained fulfillment, you'll never want to settle for anything less.

If you make the opportunity. you'll be the first in the position to take advantage of it.
