I hear of guys missing out on IOIs all the time, even my best friend who's a real player has his days of missing out on IOIs sometimes. looking back at my AFC days, you would wanna slap me about the IOIs I missed out on, the way I really developed myself into picking them up was firstly by reading what IOIs girls show and maybe a little research as to why. 2nd, and ive become good at this, I have this fun habit of watching a couple in the smoking area of the club or the club, talking, dancing, whatever...and I read their body language whilst interacting without hearing a single word of their conversation, I see if she shows any subconscious IOIs to him through her body and make a prediction as to what will happen in the next 10 minutes....this definitely got my IOI radar on and it makes things easier, it gets rid of the "does she like me" thinking so u can just focus on ur game. it really didnt take me long, just a few days observe people, ur brain will eventually adapt a system to picking them up...i watch my friends some times getting IOIs, wether they got them or not, I tell them as soon as i get the chance, it also helps u determine if the couple ur observing are together or not, really its that simple.
