The Amazon narrative on the power of the long view is based on two simple principles.
1. Focus direction on something that won't change in 20 years, or more
2. Tinker and test your way in that direction, leveraging uncertainty as your greatest asset
This is the Amazon formula for success. Focus on delivering the best and most affordable options in the shortest amounts of time. This keeps them agile and open to every new tool and resource they invent and discover in this direction.
Short view goals, like any from 2-5 years implies predicting what's going to happen within and beyond this window, which is not possible. Predictability is most reliable 2 quarters out.
So, given this intrinsic uncertainty, what should we be doing each 2 quarters? Experiment in our committed direction of contribution.
