Physical appearance plays a huge role in whether or not someone will be attracted to someone else. How well you care for your physical health and appearance is something that people can see right away, so it is worth putting some extra time and energy into while you are trying to attract someone. People will notice if you don’t care for yourself and this may make someone lose interest.  To ensure that you look your best, exercise, eat right, practice proper hygiene and wear clean, flattering clothing. Don't be afraid to capture attention. Make sure that your personality shines through and he/she knows about your likes and dislikes. Being passionate about something is very attractive and others will take notice. Be proud of your accomplishments and confident in your abilities. Confidence is something that people admire, so don’t be shy about what you have accomplished. Treat others the way you want to be treated. It may sound cheesy, but it's true. If you want others to treat you with care and respect, you should start treating others this way, too. People are more likely to fall in love with other people who have great personalities, who are polite, and who are kind to others. Let him or her see how far you’ve come. For example, if you are fit and active now, but you used to be a couch potato, tell the person about your transformation. Revealing some of your past shortcomings to someone will allow him or her to see the real you and appreciate you even more.

How would you rephrase that briefly using Vietnamese?
Chăm sóc bản thân. Tạo “thương hiệu” cho bản thân, làm việc gì đó để lại ấn tượng cho họ và cho họ biết bạn còn có nhiều thứ tốt đẹp hơn cả nụ cười. Cư xử tử tế. Cho thấy khuyết điểm của bạn.
