Waste of time?

During a game do you waste a lot of time? pacing? watching other games? thinking about other things to clear your mind... you do this natural during the course of your day whether you notice it or not. How often do you find yourself in a slightly worse position though and just completely lose concentration? You think "it is over" or "there is next game." These are signs of lack of concentration. How to build concentration? But more important do you stare at your rating or your results and say "I've made no progress." Sure you do. We all do. Whether our ego is too big to admit it or not. We have all done that. The way around it is by believing in yourself. There is no "stall." There is simply psychological barriers we have created within our own mind. There is no super secret: practice makes perfect. You get around these confidence and concentration issues by coming back to fight again. There is next game, next tournament and next study session. Anyone can attain their goals if they put forth enough time and effort!
