This is what works for me, I have told this to many people, and it has worked for those who followed through. Its not a magical spell to make anyone fall in love with you, but it definitely helps tip the scales in your favor.
my disclaimer is that this works for me, It might not work for you. I do not treat women badly in any way, and I have the utmost respect for women, same as men. I understand that this, or any set of guidelines is not completely definitive or sure-fire, but it is my way, if you don't agree, theres no need to wage any sort of comment war. I guarantee you some men will think I am wrong, and alot of women will. These guidelines have worked for dozens of people.
Step 1: Be Yourself
Some people just won't like you, and just won't click... it just won't work.
Get over it.
Lying is the worst. If have to lie to get something, its not for you, and its not worth having to lie to keep it. Girls are no exception to the human race, they appreciate honesty above all. This is a good thing to realize about all people, if you plan on dealing with them for the rest of your life. By honesty I don't mean "Yes, that dress makes you look fat," I mean honesty of character.
You have to be pretty confident, and realize that ultimately you are selling yourself--Not everyone is buying, but being confident and straightforward is the best sales pitch.
