It means you can change, if you want to! You have agency over your own life, you have responsibility over your own actions. Sure, you got a shitty start, but you're the one who decides how you're going to continue--whether you're going to play the hand you were dealt or if you're gonna change the game altogether. And that doesn't expire! My parents' dog is like ten and I taught her to shake hands last summer, you can certainly still think about trying to be someone your kids can be proud of or not.
