That would be a good term for it.
I wasn't really thinking anything. I didn't make a concious effort to "clear my mind" or anything bit after getting up early on Sunday I guess I was just too tired to really even daydream about anything. I wasn't focused, nor distracted. I thought about nothing and I guess it worked! The question is, how do I do that again?
I too have attended shoots with the "I'm just here to have fun, to heck with the score" attitude too but perhaps I've just never interalized that mindset? The differences this time were: a) I actually did very well, I made hits without seeing anything that I can remember (much less the sights!), and c) the "Zen-like" *feel* of the whole thing; almost like I was sitting back and watching a not-completely-clear Youtube POV video of a pistol match stage rather than actually being the one shooting.
That could be. I guess that, like most people, I want to do well at the thing that I'm passionate about and so I almost can't help but care, even when I'm trying not to. I think the letting go of the "care" might be my biggest challenge.
Thanks to all who answered. You've all given me something to chew on.
