In one sentence, describe what the following article is about:

One criteria often used to judge "leagues" is a person's monetary worth. Of course, plenty of poorer people date richer people, but more often than not, people tend to date and marry within their social or economic class. Therefore, if she has a lot more money than you do, she may decide you're not in her league.  Use visual clues to help you decide her socio-economic status. If she's wearing designer clothes, expensive jewelry, and a high-end handbag, those are good indicators she has some money. If you know the woman, think about the people she's dated in the past. Has she dated people who had a significantly different income than she did? That can also help you judge. That doesn't mean you shouldn't approach her if you think she's richer than you. For one, she may have just figured out how to appear richer than she is. For another, you should let her decide what makes you in or out of her league. Another criteria that people use to judge "leagues" is looks. For example, if she is much more conventionally attractive than you are, she may consider herself out of your league. Just like economics, people often tend to end up with people who are similar to themselves as far as attractiveness goes.  You may find it easier to judge her looks than your own. However, to truly gauge whether you are in her league, you need to be honest about your own looks. Are you just an average-looking person, while she's got exceptionally good looks? Then she may be out of your league. If you're not sure how to judge your looks, ask a good friend to help you figure it out, someone who will be brutally honest with you. Just be sure you can take it. Even if you're average or below-average in the looks department, you still shouldn't count yourself out. Let her do that for you after you approach her. Plus, she could come to find you more attractive over time if she enjoys your personality. In addition, education and intelligence is another important part of considering if someone is out of your "league." In other words, if she has a doctorate and you barely finished high school, that may not be a good match because you may not have the same pursuits. Of course, education and intelligence are not the same thing. You can be incredibly intelligent and only have a GED. Nonetheless, if she's smart and sharp, she's going to probably want someone who can keep up with her. If she's very into healthiness and you're not, that could be a barrier. You should be able to tell on some level. If she's muscular or is obviously abstaining from unhealthy foods, that's a good indicator that a healthy lifestyle is important to her. It's not that you are less worthy if you don't enjoy the same type of lifestyle. It's just that you may find that your two lifestyles aren't compatible. While having different beliefs from someone doesn't constitute a "league," it is an important part of attraction and connection. In other words, if she's religious and you're not, that could be a significant barrier.  Other barriers could include the issue of marriage (Do you both want it?) and kids (Yes or no?). You may also have issues based on what kind of life you want. For instance, if she wants a fast-paced urban life but you prefer suburbia, then you may not be compatible. Money, looks, education, and social status do obviously play a role in choosing a mate. However, many other factors can make you more attractive to a woman, including being a competent person or having a warm personality. In other words, don't dismiss your other good qualities just because you've judged her to be "ahead" of you in certain areas.
Consider economics. Think about her looks. Check educational level. Pay attention to her fitness level. Consider religion and lifestyle factors. Remember it's not all about leagues.
