People write poems about the love of life, for people, for God. For some they turn out very good, for others they are weak, naive. This is understandable and natural, because the level of skill in people is different. There are authors who address poems to themselves. What is the reason? It is impossible to give a definite answer to this question, because everything depends on the person.

Due to a sharp change in the hormonal background, adolescents perceive everything too sharply, become touchy and vulnerable, conflict with parents, relatives and teachers. It seems to them that adults do not understand them at all, they are indifferent to their problems. If unrequited love is added to this, the student may become very depressed, deciding that there is no happiness in life, no one needs him, no one loves and understands him. To escape from these oppressive thoughts, the child composes verses about love addressed to himself. Such verses are a kind of "cure" for the resulting depression. Such creativity speaks of resentment at the outside world.

The opposite situation can also happen, for example, an impressionable teenager is so happy after receiving reciprocity from a loved one that he is overwhelmed with emotions, he wants to tell the whole world that he is loved. So we get the lines about self-love. In such verses you can see a note of joy and happiness.

At a more mature age, this can be explained by other reasons. For example, a person for some reason does not develop relations with relatives, friends and colleagues, he can not arrange his personal life. He is considered arrogant, while he is simply too impressionable. Creating love poems, the author, as it were, flees from unpleasant reality, explains to everyone else that he is actually not arrogant at all, he has a lot of advantages and there is something to love him for.

There are times when the author creates poems about self-love, being sincerely confident in his irresistibility, high qualities, charm. He considers himself a model, a standard of all virtues. Such a person exalts himself. This is already a cross between the strongest egoism (on the verge of egocentrism) and mental disorder.
