A man's reach should exceed his grasp: why Netflix killed Blockbuster

Blockbuster chief of digital strategy is quoted in Fast Company:

You can always say I wish I did X and not Y. But if you asked me in 2009 whether we'd be the only one in the mobile space selling movies other than Apple and whether we'd have Blockbuster On Demand--never in my wildest dreams would I have aimed this high. [emphasis is mine].

What's the point of a strategy if you can execute on it and pass your own dreams? No wonder my money is on Netflix FTW.
