  2. Data is not going to be perfect. Data out there is always going to be messy, incomplete, even discombobulating. That’s just reality. So there’s no point in waiting for the perfect dataset, there are still insights to gather. But at the same time, great data may also not lead anywhere, which leads to the fact that -
