You have to find someone that you have great respect for, and someone you can communicate with, because you have common interests and backgrounds.  Many people fill out those bio-marriage forms online and pay a web site to advertise for them, to find a suitable person to marry.  What you do is, fill out all kinds of personal information such as, name, age, education, culture, parents names, occupation, religion, address, salary you earn, special interests and hobbies, names of all your brothers and sisters, and any other details about you that are impressive to other people.  Then the interested people will contact you at whatever address or phone number you provide; and you meet the other person and their family.  Take this process slowly because marriage is a partnership for life.  You will both know in a short amount of time, whether you have found the right person to build a good life with, or perhaps just a new friend.  You repeat this process until you find a match that works for everyone.
