A lot of times a chick will reject you because of how you spit at her, like you're way too confident and cocky with it...or on the flip, you are way too timid and insecure with it, chicks don't like that either. In those situations they're just playing hard to get because your approach is off, put a little more effort into that initial impression that you leave and them buns is yours easy.
If you're getting rejected because you look crazy though, that's a whole other something,
. Hit the gym hard, get your money up, get your grooming together, etc... somethin like that. That man Quilly like 5'1 tryna shoot at chicks like he's a 5-time NBA all-star,
, humble yourself lil guy.
