Pay attention to all your thoughts, emotions, actions. Something unknown is waiting there for you. Most people know nothing about themselves.
If you are angry, it tells you that there is something within you that is resisting the world now. Why is it resisting the world? Go into it. Try to understand.
Same with disappointment. You lost something; some desire was not met. But what is the fundamental desire?
Similarly, attraction. Superficially, probably what you are looking for is desirable features, a few other things. But what is it that you really want?
Whenever you would go to the root of an emotion, you would discover something important about yourself. We all want one particular thing. Our way to ask for that thing depends on our biological constitution.
