What is required for one to win the heart of a person of opposite sex

To get to know and accept the person as they are now, then work the H2IK sequence or (hell if I know) from there. That takes time and most people are too impatient to get something without going through the sequence. Everyone is different, so don't assume the same line will work with each person. Take every person on their own individual flaws and merits. May be clear as mud, but that's how I see it.

Hope that makes sense.

big fat wallet

I don't understand u quite clear

Nu sometimes they don't want to come near you

Well, you're users name is probably not the best as that's the first thing they see
Ilovelman, sounds like you love men!
Problem is you can't change it.
You must have missed out the "L" to say 'lovely' man

Wit and patience

I have a small skinny wallet but I carry an American Express card. I never leave home without it.

I'll try change that Mikey

Every girl is different man, you can't just use some formula. Get to know a girl and then ask her out. The only consistency is that she has to find you attractive. But what she finds appealing, is up in the air.

I’m not sure anyone can answer this question, only what is required for someone to win your own heart, if win is the right term.

Good luck.

hahahahahahahaha
I may have to steal this line :-)

Pretty easy.
Find someone of the opposite sex.
Stick around them as long as they're okay with it.
Pay attention, use that thing between your ears to its potential meaning don't try to be purely objective (rational and logical) nor simply follow emotional/hormonal impulses.
Learn from interacting with them what is required to win their heart.
Keep in mind they're finite and fallible human beings too.
So you can't simply rely on what they tell you or think will work while at the same time not completely dismissing what they say.

If you're kinda lazy and need a universal answer, then go out and find a woman that lives up to a stereotype, then help her fulfill the stereotype (her identity) while establishing a more dominant position in social reciprocity.
e.g. golddigger.

This should be easy: run as fast as you can and stay single. I had a friend..well he was a friend until he stole everything from me so I decided not to trust anyone anymore. Sometimes these so called friends can make your life a living hell. The decision is your in the end.

I like a simile to looking for the key to a great treasure.

Ever look closely at a key? I real expensive key? It's complicated.

And it's unique.

And so is the answer to your question. You don't, I actually suspect, really want to "win the heart of a person of opposite sex." You want to make a life with a particular person, who loves and wants you for the particular person that you are.

Like finding the exact key that opens the lock of a particular treasure.
That means that any general advice you can get, other than the basics of self-knowledge, and the usual attention to the reality of the other person, really wont help you.

It's a bit like I keep hearing about finding someone to have sex with. If all you want, is to have sex with someone, ANYONE, it's not that hard to do. As long as you really don't care about the other person (or thing), and you have no personal standards of decorum at all, you can probably have sex with SOMEONE fairly regularly. But if you want to have really meaningful sexual activity with someone who you care about, and who cares about you, that gets a LOT tougher.

Good luck.
