Returning to The Hundred Rules of War:
"When entering a confrontation, Samurai should neither look back on the path travelled, nor what is off to the left of right."
Most of us will never enter battle, and many of us avoid confrontation like a plague. I think that's why, when we enter into a confrontation (an argument, a discussion, or a physical altercation) we've got no idea what to do. Panic sets in. We become overwhelmed with everything going on around us and lose focus of the task at hand.
Focus on what's ahead and drive through it. Don't allow yourself to be distracted.
I see this a lot as a teacher. High schoolers in particular might see the confrontation as a big assignment that needs to be completed. Some (more these days that i've noticed in the past) become overwhelmed with details and other happenings that simply don't matter and are not relevant to the assignment.
Do you remember the last time you did something distraction free? It really is an amazing feeling. Each morning I get to work a little early, shut the door, and read (usually something nerdy) for 15 minutes. No phone. No e-mail. No worries about the day ahead. Just pure, uninterrupted, focused reading. Focus=freedom. Enjoy some of it today.
