Be yourself, and don't let anyone pressure आप into doing stupid crap just for the sake of being "cool" and "hip". It's not worth it! Never feel bad for being different या holding onto your innocence. Your life should not be rushed, so please don't get in any hurry to grow up. And if आप have parents that suck and/or don't care about you, just remember that आप can always find someone who does.
Now for the spoiled brats:
आप aren't entitled to crap, and we adults aren't your slaves. आप want something? Get off your butt and get it YOURSELF. अभिनय like a spoiled brat won't get आप anything except a butt-whipping. That is all.
