I know it depends on each person, but what are some characteristics which work best?

Apart from looking your best, should you be funny constantly?
Relaxed and funny every now and then?
Extremely sexual?
Aim at just being seen as "very nice, friendly" while escalating slightly?
Being completely up yourself/slightly rude/arrogant?
Act disinterested?
Act very interested/being obvious? eg "Oh...helllooo " (thats a joke, but you catch my drift)

What seems to work best? I have a feeling often that maybe im being too up myself, or trying too hard to be funny etc
For example if a girl tries to hug me ill be like "Please dont do that" (in a half-serious way), and im thinking "Hey, maybe ive got the wrong idea of being a challenge?"

Or if i meet a girl I find attractive, ill be confident yet not pay her much attention at all, then be like "Oh cool, nice to meet you" and keep talking to other people.

So my two points of query are, whats a good way to behave for a good first impression?
And are my current actions not helpful?

Oh my god you are way over thinking this stuff!

Okay first of all I want to tell you that there are a lot of ways to get a girl, not just one or two. There are equally just as many to not get a girl. I have seen guys go up to girls and be 100% sexual off the bat all the way through the F-close saying things I wouldn't dare repeat but it worked for them. I've seen guys be funny most of the way through. Then there are others that just follow methods step by step and that works for them. Some act disinterested, some are direct. ALL GET THE GIRL. The point is find out what works for you and who you are and stick with it!

Another thing I'd want to point out is if you are in your head this much thinking about it here then I wonder where your head is in set. Are you focused on the girl or are you contemplating your next move? Getting the girl is all how you do things and if you're in your head and not paying attention she'll know it. RELAX, calm down, clear your head, focus, work on having a good mental attitude, and enjoy being in the set. It'll happen for you.

what i found to work best at least for me is don't go actively looking for a girl. when i go out i look forward to meeting with friends or enjoying the night. The reason i do this is to be in a relaxed and natural mind state. I don't go out with intentions of hooking up/closing with women, but if they happen to be where I am and I see an opportunity/opening i will take it.

When it comes to gaming there many rules and non at all, women being fickle beings means most times you can't rely on any one strategy. Yes having a rough idea of what you want to say is always a good way to start conversation. Just don't get bogged down on all the fiddly details of what you think you "have to say" if you get my drift.

You want to appear cool/natural even if it's the furthest thing in your mind, no woman wants to see a guy fumbling or reaching for conversation. They want to see that guy talk with ease and poise.

brilliant, thanks
"youre overthinking this" is all i needed to read haha
