Unfortunately, the "cool kids" part gives you away. Like so many things in life, you win by opting not to play the [horribly broken] game.
Being secure in your identity means you don't have to partake in idiotic status signaling like this. Why? Because you just don't care about all the things you're told you should be doing in order to be 'relevant.' You're happy just to be you, and to do what you need to do. Culture still weighs on you, but it doesn't have to dictate your life. And you know what happens? Over time, people become more interested in you because of this. They may question you, but they may also envy you.
The path to discover one's true self is a lifelong journey, and I bid you good luck on it.
