This is a relatively quick read - but it is excellent.
Full of great context and ideas - well explained.
There's subtlety in the idea of business becoming more social, more conscious, more ethical or "better" - whatever you want to call it. And Umair does a great job of making this subtlety plain - it requires a paradigm shift, not just harder thinking within our current models.
I also liked the sections around reinventing how we think about strategy, business vision and mission. Some really painful examples of mission statements from the 1990s!
If you are interested in how a tidal wave of activity is hitting business in the next few years - this is a great starting point.
