Your question prompted a good guffaw on my part.. partly because sharp truths are kinda funny, and partly because I recognize my own reactions in your words. Maybe if you looked at things slightly differently, you'd approach it a little differently.
I look at the things in my life and measure their importance to me, and topping the list (no particular order) is marriage, family, keeping my business solvent, my hobbies, politics, my religious faith, understanding current events, understanding history and economics and of course, all the technical stuff my business requires of me.
After I look at how my attention and energy is divided among those topics, I begin to realize why I don't care anything about a wide array of celebrities, TV shows, and other icons of pop culture. And realize that those who place those things in position of great importance are failing to elevate the things that matter to their rightful place.
It means that people who devote their attention to what Miley Cyrus wears, who is "hot" this week in the music and social scene, and all the other celebrity driven things that grace the covers of a huge array of magazines, what Oprah is doing, etc, are not putting things of real importance in a priority in their life.
Do you REALLY want to adjust your life, to be able to be social "fits" with these people? Why? They are NOT the only people around you. In fact, they're generally a minority. Start looking around you and looking for those people who do NOT live and think that way. It will improve your life and thoughts as well. Oh, and, welcome to adulthood, the real one. Glad to have you.
