This is not about the book, it is about life. Strategy which worked yesterday on something doesn’t work today.
It is like tortoise and hare story. Every time,you revisit and where you’re heading.
We travel,study,work lot. Once we reach somewhere you get stuck. You blame some one for failures.
Believing in evolutionary than revolution would work.
Constant change in the plan to meet goals would help.
Learning from everyone’s mistake and taking right step would help.
