When we use data to answer questions, we fill in the blanks and swing towards the answer we want to have. Torture your data long enough, it'll tell you anything.
On the other hand, use your data to expose questions and you'll learn what's important. Why is this happening? What's going on here? Why this spike? Why is this so low? What worked best? Why's this group acting differently? Who's leaving us? Is this a trend?
The best tech founders I know wake up to their data dashboards, comparing graphs, looking for weirdness. They start their day with an important question to be answered, and they go find that answer. They end each day more informed about their business.
