Don't tell your buddies about Game. Ever...unless they beg for tips.
Never give unsolicited advice: I learned this the hard way by scolding an AFC who was embarrassing himself by mouth-breathing over a chick. It turned into an argument & later I felt like I had something to prove around him. Huge AA.
Pleasant surprise is better than disappointed expectation: Now I just bail from the unsuspecting AFC buddies to open a set. It's a huge rush because I know they are watching me. After number closing, those guys were mouth-breathing over me. Haha. If you don't give them high expectations, they will be impressed with any approach outcome because YOU have proven that you are the one with enough confidence to try. This is also why women frequently find men more attractive AFTER the opener than before. Confidence is sexy.
