By age of twenty, you know you're not going to be a rock star

By age of twenty, you know you're not going to be a rock star. By twenty-five, you know you're not going to be a dentist or any kind of professional. And by thirty, darkness starts moving in - you wonder if you're ever going to be fulfilled, let alone wealthy or successful. By thirty-five, you know, basically, what you're going to be doing for the rest of your life, and you become resigned to your fate.
