Definition of strategy
This is a collection of definitions of what strategy is and isn’t.
Strategy is picking the game. Execution is getting very good at it. 
Business strategy boils down to making a choice your competitors wouldn't. If you haven't, you don't have a strategy, you're just competing on quality of execution. 
Manipulating the environment to your advantage is the essence of strategy. 
Strategy is no more, and no less, than the discipline of making good choices in order to succeed.
