if you hit on chicks your going to end up in the friend zone. I would say stop hanging out with the "friend zone" chicks for awhile, and meet some new ones. you can go back to the other ones when you refine your strategy
dont try to hit on them at all, just act like they're not hot shit or anything, and if you dont go for them they go crazy about it because alot of dudes try to go after chicks.
chicks are used to being sought after, so if you basically half ignore them they come back to you like moths on a candle.
I'm just speaking from experience so yeah.
