Be yourself, unless you're a filthy unwashed mouth breather. Don't try over play who you are because MAYBE eventually a girl is gonna be there when taco bell gives you the shits. Put your best foot forward, if you can make her laugh then you're usually good to go. Make her happy but never cut off your own arm just to do so. Pay for everything on the first date, budget that shit out. Call it misogynistic if you want but if you make her pay for stuff on the first date you're gonna come off looking like a scumbag. Don't rush anything. Read her body language and the moment. If she's giving you signs then go for it.
