One of the main things I have learned over the years from my martial arts, military service, and strength & conditioning is the importance of focusing 100% on the immediate task at hand.
I remember many times having the door position on a night jump from a C-130; the only thing that mattered was seeing that parachute open within 4 seconds. The was my complete focus. I wasn’t thinking about what I was going to do once I hit the ground, I had to get there in one piece first.
The same thing goes for lifting. You have to concentrate on that one rep, not the one you just missed or the one you hope to make next. Just this one, nothing else matters at that moment.
You cannot and must not let all the chatter of this crazy world invade your thinking!
Shut out the noise, the regrets, the anger, the disappointments, the busy schedule and all that other garbage and just make that one lift.
