The author is certain that the three most important keywords for love are similarity, equivalence and respect. The author is convinced that in the early stages of a relationship, people are more likely to fall in love with someone who shares their interests, values and views on love. When deciding whether to get involved with the other person, people will consider the equivalence of the two parties in terms of appearance, wealth, status, knowledge, character and personality. The author makes it clear that love is not a zero-sum game of self-esteem. It requires mutual respect from both parties. To maintain a long-lasting relationship, both people must learn to give and receive "self-esteem massages" and respond positively to compliments.
