Sometimes when staging my mind is going a million miles an hour and not focusing on task at hand. I am mentally reviewing my check list, making sure I got everything, then I start thinking about the last pass and how the car reacted, what can I do better. What do I need to focus on and the next thing you know the stupid lights are descending and o crap I gotta go! Totally space whatever it was I wanted to focus on and just react. Yep another opportunity to learn wasted I just drove the dumb car! Oh well, it is better than sitting at home! Focus and concentration are exceptionally hard to do if you actually focus and concentrate on doing it!
