the people you chose to be around you, kinda lets you know who you really are. you'll never completely object to someone's lifestyle and still hang around them.right? that leads to you accepting their lifestyle and more than likely there's gonna be a fraction of that person's lifestyle in yours as well.
now everyone most probably is affiliated to multiple cliques.and each of these cliques have a high chance of being defined by the fact that they advocate similar lifestyles. and what does that say about you.
your lifestyle's components probably vary. i would guess 4 major components and 3 minor ones would pretty much define a person's lifestyle.so essentially your lifestyle would be the intersection of all the different sets. that is, each cliques's major components make up a set.
i've most probably lost all of you who're reading this now and well this is more of me thinking aloud. one last random point, a subset. a set within a set, and a clique within a clique. what defines it? differentiation.outcasting.backstabbing.lies.putting up a front.cheating.pretending.
