If you are a founder, please read Jeff Bezos’s letter to Amazon shareholders. He does a great job of distilling why it’s so difficult to build a great company.
What he describes as a Day 2 company would include the majority of businesses around us, including many market leaders. He describes Day 2 as sometimes taking decades – extreme slow motion.
It is very, very difficult to stay in Day 1 mode. I am not even sure Amazon’s succeeding there, as it’s also tough to tell.
However, customer obsession is one way you can try to stay in Day 1 mode, and avoiding proxies and celebratory narratives will help you along the way. However, it won’t help you feel good.
Entrepreneurship rarely feels good.

We get approached by ~1200 companies per year and spend some time with about 400 of them. One of the key filters for us to identify opportunities we may be interested in is how quickly we can grasp the basics of the business’s economics; i.e. how value gets created.
