There's never been any game plan or thread through my career. It's just happened that I've ricocheted from one interesting character to another.
Thinking about your role will automatically get you in the frame of mind to get your strategy and game plan right before you step onto that field.
In every aspect of life, have a game plan, and then do your best to achieve it.
I'm always surprised at what I actually end up doing because I don't have a strategy or a game plan, especially now that I'm making my own choices.
