@Silentman: I agree, both approaches on the surface appear to clash, but if you dig a little deeper, you kinda see that they are really just two sides of the same coin. Even Rune commented that there has to be some sort of happy medium, as each extreme is unsustainable....it's just it's difficult to find it. The 3-Second Rule works, but only if you come prepared with good game prior to the event.
As Neil Strauss wrote in The Game, "Perception is reality"....if you start thinking of every bad thing that could possibly occur, chances are that you will either fail exactly as you imagine it to be, or you'll chicken out, and end up reinforcing your own social anxiety. And as I've found out recently, trying to get rid of a lifetime of bad social habits can be as tedious as breaking up a house-sized boulder with an icepick.
So what's the magic bullet? How does one find the right balance between "living in the now" with quick-draw analysis?
