The first rule: subjectivity, in a relationship to maintain their own subjectivity (do not go to study whether the other party really love you. It doesn't matter.), more attention to the other party's character character, do not seek to change the other party. The second rule: screening, there are 8 billion people in the world, more need to be screened. Third rule: Sincerity, keep yourself real and sincere. Lies and personas cannot last a lifetime. The fourth rule: avoid disaster, try to avoid bad family of origin (even the best-looking rose in the desert is highly toxic), defective temperament and character, as well as the bad habits of pornography, gambling, drugs and tattoos. The fifth rule: decision-making, the cost of silence does not participate in major decisions (do not eat chicken ribs because you pay a lot.) The sixth rule: do not force, do not force to stay. The seventh rule: the spirit of contract, marriage, no matter how poor or rich are willing to accompany you for life. The other half has the spirit of contract is more important than all the above six rules. Regarding love, in psychology I have always believed that there are shortcuts and triggers that can be utilized to capture the heart of any person. Over the centuries, I think there has been a whole system where each person is like a broken stone, not quite the same but can be put together.
