1. Be RICH. 
This is important for you, but not for her. For her, #2 follows.
2. Spend MONEY on HER. 
This is the most important thing for her, whether you are rich, have any money, or must lie, steal, or kill to do it.
3. Be TALL. 
Of course you have no real control over this, but if you don't do it, she will secretly & forever resent you for it & it will come out of left field to smite you. Preferably be about one foot taller than her - not for comfort or aesthetics, but because you are a trophy &, as always, the bigger the better.
4. Be a MINDLESS ZOMBIE RULED BY HER. 
Forget what you've heard about submissive asian women. They actually rule every relationship with insidious & painful, passive-aggressive, guilt-evoking, whiny, crying mind-control.
5. Have the EMOTIONAL STABILITY OF A 4-YEAR-OLD. 
She will be impressed & enraptured by your delight at the sight of Hello Kitty, stuffed animals, puppies, kitties, duckies, bunnies, as well as chocolates, shiny jewellry & other trinkets & knick-knacks. Also, she will understand perfectly well if you pout over the smallest perceived slight or slip & demand to be appeased, assuaged, or made up to. If you behave any other way, she will never understand it.
6.Dress like a PRETTY-BOY GEEK. 
This will save her the trouble of replacing your wardrobe & dressing you herself.
7.Remove EVERY HAIR ON YOUR BODY EXCEPT THOSE ON YOUR SCALP. 
The sight of a whisker on your face reminds her that somewhere inside you, something is trying to grow. You must not grow - you must be as unchanging & constant as the firmament.
8.There are NO MORE RULES to making your asian girlfriend happy. 
If any situation arises which you feel the rules have not addressed, you are mistaken - immediately refer to the primary rules #1 & #2 - they are the solution in every such case.
