Do you ever play out every possible scenario in your head before the scenario happens?

In other words… do you consider every possible outcome your mind can conceive before a situation happens?!? Ponder every possibility?!? Play them all out and process the best combination as a response… only to have the situation throw a variable out that you did not consider and cause you to adapt “on the fly”? Did you learn from it? Did it make you improve upon your ability to add yet another set of scenarios from the infinite possibilities to your next situation?!? Can you ever cover them all?
