Many of the so-called barriers that we try to reach in golf are simply arbitrary numbers. I get that it sounds cool to say that you shot 69 instead of 70, but at the end of the day, it's just 1 shot. 

Winning golf tournaments and the scores you shoot themselves are results. Both, in many ways are out of our control. I suggest focusing as hard as you can on the things that you can control...like executing the proper shots at the right time. 

The results will take care of themselves.
