no, they are arbitrary bullshit you tell yourself to make you feel like you have control or give you ready made excuses to keep making the same mistakes, over and over and over, rather than trying something different that might make you genuinely happy.

someone's age, or height, or amount of income/wealth isn't going to make you happy and fulfilled. but you tell yourself it will because it feels like it's something you can control. of course, the irony being the other person could just lie about those things...
