Don’t give others the power to control your emotions. Those are only yours and it is only for you to manipulate.
Time after time you see a promising athlete come out of college and go into the pros only to bomb out. He or she had the best athletic ability, yet could not cut it at the professional level. Others might not have great athletic ability, get picked late in the draft and go onto become super stars. Tom Brady comes to mind as someone who wasn’t particularly outstanding in college who has gone on to be a probable first time inductee into the NFL Hall of Fame.
Personally I have seen the same. I spent many years in the US Army Special Forces. We would have tryouts who while in the best physical shape just could not make the grade to be a Green Beret. Others, who would seem to be nondescript, would pass the Special Forces Qualification course with flying colors and go onto to be an outstanding soldier.
You are probably asking yourself by now what is the difference? What do you need to perform at the highest levels, which is even more important than physical ability?
