Wondering at madness that compels people to do a PhD. Ruins your back, finances & social life. Arguably generates zero return on investment. Makes you talk to yourself in your sleep & listen to obscure music instead of writing the ground-breaking stuff nobody else can write for you. Eternal blinking at a blank monitor. Every day, you realise how little you, and everyone else knows about anything, and that the world still does whatever it has to do regardless.Sure, I was made for this.
