If someone has to even ask how to marry a rich guy, it's safe to say they likely won't. But for the thread's sake, here is some common sense advice:
1) If you're not in their location, be it that you live or hang around their neighbourhood, visit the same spots they do, work/attend school in the same places as them, holiday where they do or attend the events they do, you're not going to even have the chance to "show your personality".
2) How they spend their time throughout each day will tell you where to meet them. It will also tell you what they care about or are interested in. Your second biggest barrier will be commonalities. If you can't relate to their upbringing and experiences, speak their language and understand their jargon or speak intelligibly about subjects they care about, you won't connect with each other emotionally nor will you have opportunities to spend time with and bond together.
3) Your third biggest barrier will be his family, social circle and culture. If he depends on his family in any way or is particularly close with them, if they hate you, you're out. Likewise with the other two. You have to know how to integrate yourself into his social sphere, otherwise you'll stand out like a sore thumb and the constant critics up in his ear will turn him against you.
4) There are moids in every financial bracket, but if you're going to compromise your standards for the hope that you'll have access to your partner's funds simply off of the basis that they have a lot of it, you'll find yourself sorely mistaken and taken advantaged of. Rich people in general are stingy unless they hold "traditional values" in high regard. The downside, however, is that they'll also value traditional gender roles as well, and much of the thinking that comes along with it. His money doesn't suddenly become your money no matter how much of it he has.
