It really depends on preference, some people have dynamic personalities and some have static personalities, some people are serious, others are lighthearted. Being the center of attention in your social circle or having an appealing or exciting lifestyle are positive traits that could come across as attractive or at least attractive to the typical person. However, there are many factors when it comes to attracting someone, it really depends on the person.
It also depends on the culture, people I have met from Eastern Europe, Germany and Poland tend to value thoughtfulness and seriousness as opposed to Americans that prefer burlesque humor.
