Planning versus Execution
Wally Bock hits one out of the park with this post on why people would rather plan than execute. An excerpt:
Planning is all about possibilities Execution is all about accountability.
Planners analyze opportunities. Execution is deals in limitations.
Planning is intellectual fun, with no responsibilities. Execution is all about work and there's lots of responsibility.
You can declare a victory when you produce a plan. Execution never ends.
