The proverb says that birds of the feather lock together. This may be true in some cases but generally speaking, the two individuals need a common interest. It may be playing video games or horse riding. It doesn't matter; you just have to be sure that there is, at least, two things that you like to do with the other person. This will play a big role in the couple's future life together.
Can you communicate to each other?
This is another key point. Two persons who cannot talk to each other just cannot live together. For a period of time, it can be possible but for a long-term relationship, it does not work. The two peoples have to share their feelings (happiness, likes and dislikes, anger, etc.) to each one other. And once again, we repeat it: communication is the basis of a long-term and happy marriage.
These are just few tips but the decision is yours. Be who you are, be positive, define what you want and what you do not want and finally choose someone that you can talk with and who has a common interest with you.
This step is very important if you really want to choose the right partner. You have to know yourself. Some people are searching in all corners of the earth for their soulmate but come back in vain. One of the reasons of that failure is that the bachelor did not ask himself. So the, before loving someone, before making your choice on the right guy or girl to marry, start by asking yourself the real questions: who are you? What do you want? What are you expecting from your partner? What do you like most? All these little questions may seem tiny but are very important. It is after answering these questions to yourself that you can start defining who you are and what you really want.
Be positive and keep smiling
After knowing yourself, you can now begin to change your mind. The next key for alluring your future wife or husband is being positive. By being positive, people will automatically call on you, run to you and would like to by your side because of the energy you are spreading all around you. Don't worry, it's metaphysical（形而上学的）. Keep smiling, not in blissful ignorance but the acceptation of the reality: that you are what you are, good-looking and valuable. These two steps are more than essential. It is all in the attitude.
What do you want?
There is no formula in love. You may already know the type of guy/girl you would like to date and that is correct. You find your love and that is all. If you have not yet defined clearly what kind of person you want to be your husband or wife, do not worry. These are things that have to be discovered solely and patiently. The person may not be what you have been expecting, but if there is love, communication can begin.
