execute - execute - execute

The worlds best strategy is worth absolutely nothing if you do not focus on execution! 

Strategy is in my terms (and many others) a description of how you come from A to B.

A is where you are right now!
B is where you want to be in the future (near or far)

Strategy is simply the plan for getting there!

Example:
A: I am a little overweight, and not in very good shape!
B: I want to loose a certain amount of weight and be able to run 10 km

Your strategy (plan) is a detailed description for how you get there. It could consist of a dietplan, a running/training exercise and a lot of other stuff - BUT BUT BUT if you don't execute, you will se NO results, even if the brightest experts on diets and the top running coaches made the strategy for you! You need to implement the strategy in your daily routines and everyday life - or the results will be absent.

by the way this principle also goes for businesses!
