I know this isn't easy. I always shot my best when I was able to not care about anything at all. Not points, nor time, nor placement. Just get into the shooting without caring about it.

Being an "observer" when shooting always produce the best results for me. If I care at all about what I'm doing, then it takes away from doing, and performance suffers.
If you watch Travis T. shoot the 3 reload 3 reload 3 in just over 3 seconds during the last show of 3-Gun Nation, if you look into his eyes, they are totally empty and devoid of emotion, he is just doing what he has trained to do and he makes an amazingly difficult feat look incredibly easy.
If you don't trust your ability (whatever level it is) you will have a very difficult time performing to your abilities come match day.
