If there’s one piece of wisdom that this simple pilgrim would like to impart upon you: have the courage to start with the customer. My biggest regrets are the moments that I let a lack of data override my intuition on what’s best for our customers.
Data is always a story about the past, but the future isn’t always like the past. Smart people are going to be talking more and more about the limits of data for decision making. It’s better than nothing, but it isn’t everything.
