Form human relationships. Famous human Aristotle is remembered as saying: "Man is by nature a social animal; an individual who is unsocial naturally and not accidentally is either beneath our notice or more than human."
In your life as a human, you will meet people. Some will make you feel good - these are "friends." You may feel a sexual and/or romantic attraction to some: Such a person is a "romantic interest", who can develop into a spouse. A life lived alone is not a fulfilling one - spend time cultivating healthy relationships for a richer, more emotional life.
