First of all, because their friend group is a fictionalized ideal, rather than a realistic norm for most people. They're showing you something aspirational, but not something everyone can necessarily expect - the point you take away should be more about the improvement in yourself cultivated by pursuing that goal, than it should be about feeling disappointed or like it's some sort of flaw in you when that goal isn't not easy or you never really get there. It's the journey, not the destination. Second, per the above, it's about the work, not the result - have you tried being someone people *want* to be in a friend group like that with?
