First let me say thank you. I've been a lurker here for a long time and thanks to you guys I have improved my game tremendously! I've improved so much so that I have the fortunate problem of too many women coming up to me. I go to a small University so I see a lot of the same people around all the time and recently Ive had girls who I had done warm up sets on at parties weekends before, and a few randoms, coming up and approaching me around campus now. The problem is they often catch me off gaurd since in my mind they are not anyone special. So my question is how do I properly get myself into the right state when I'm not necessarily looking for tail.

TL;DR How can I quickly get into the proper state of mind when approached by girls and I'm not expecting it?
