If you're looking for pick-up lines, I'm afraid I've got some bad news for you. Pick-up lines are a short-cut solution which seem appealing, but don't work for average guys in practise.
Women will see straight through you when you use them. They'll reject you, and you'll just go away feeling worse than before. Ask any guy who is a natural with women, and he'll tell you that it doesn't matter what you say to a woman; what matters is what's going on inside you when you say it. This is why your mindset is soooooo important.
To be successful using pickup lines, you first need to have a confident abundance mindset, and be detached from the outcome when approaching a woman. This means you don't mind how things work out, because you know there are literally millions of other women you can talk to if this one doesn't work out.
Then you need to be able to sustain an interesting conversation which develops and maintains the woman's interest in you. To do this best, you need to have a well-rounded, interesting life.
If you don't have an interesting life or the confident ability to sustain a conversation, you fall on your face straight after the pick-up line has been delivered. And the irony is that once you have these things in place, you won't need to resort to cheesy pick-up lines in order to attract women.
So pick-up lines are only useful to men who don't need them anyway! But the guys who sell books full of pick-up lines don't actually tell you this in their sales pitch.
