This is great advice. I would add it helps if you are well-built, well dressed, good looking and socially proofed in the venue. For most guys on here I would say they are below average in looks, either too skinny or too fat, by themselves or with one wing knowing nobody in the venue and poorly dressed. Also intention behind eye contact and if you are "smiling" with your eyes and projecting a "you'd be lucky to have me" vibe or projecting a weird, nervous vibe i.e. weak inner game is going to determine how they react.
