When the old-you disappears.
Growing up doesn’t always mean creating a life for yourself - sometimes it’s just growing out of your old one. You go your whole life defining yourself in terms of something. Maybe even multiple things. The things you do, say, think.. The way you act, the stuff you like, the people you hang out with. But one day you wake up and none of that matters anymore because you’ve decided, today - today I want to be someone different. I like strangers because to them, you’re anything you want to be. You could be the furthest from you that you’ve ever been, if you really wanted to. They wouldn’t know the difference; and they never will. But it’s kind of scary, you know, just giving up your identity. You’ve probably planned out a rough destination of your fate in terms of those defining moments and characteristics. Maybe you figured out your future self by extrapolating your past self. Despite how hard it is, I don’t think it matters who you were, or what you thought you were - or even what you had made yourself; ‘cause who are you now? That’s the only thing that determines anything.
